How to Restore Desk-Damaged Physiques with Calisthenics

May 9, 2017 By Adrienne Harvey 23 Comments

Years ago, well before the PCC, and just after Convict Conditioning began to get extremely popular, I heard Andrea Du Cane say that we shouldn’t live in the posture of our sport. In many cases, we should also not live in the posture of our work.

It seems as though many of our clients (and in some cases ourselves) spend the majority of their working hours seated at a desk looking at a screen, then spend hours staring at a small screen. So, let’s take a moment to work with some do-anywhere calisthenics exercises to help build healthy habits while undoing some of the desk-damage so we can continue to help our students, clients, and ourselves safely build strength.

In 6th grade, a brilliant friend (math genius and fellow computer nerd) and I would get to school early to boot up a lab of dinosaur-era computers. Already at that young age, my friend had the dreaded forward leaning head, hunched shoulders, and rounded upper back from hours and hours of programming. Thankfully, I was still spending a reasonable amount of time playing in the backyard on the monkey bars—while getting regular reminders from Mom to stand up straight and keep my shoulders back—which saved me from the same situation.

But, pulling long hours at work, then tapping at tiny screens has left almost everyone pretty susceptible to bad habits and weaknesses that can hold us back in our calisthenics training—and in our everyday enjoyment of life.

First, for those of us who are instructors, it’s important to remember our scope of practice. If a student or client is in pain or has a medical issue—or even if you’re just unsure about the situation—always refer them to an appropriate medical professional.

As much as it would be great to think that a standing desk would solve all the sitting related problems of the world, some of us have noticed that intense cognitive tasks requiring full concentration and extreme focus just don’t seem to go as well when working at a standing desk. That has definitely been my experience, as my typing speed and overall productivity seem to suffer if I try to do highly mental tasks at a standing desk. So, under the assumption that we or our students/clients will need to work at a desk for a significant period of time most workdays, let’s discuss how we can help.

We already know that it’s important to take breaks from seated work. I’m a huge fan of the Pomodoro technique—it can also boost productivity at the same time. Basically, set a timer for 25 minutes of work, then take a 5 minute break to walk around, do a few movement exercises, then repeat the 25min, 5min cycle four times before taking a longer break.

Poor posture habits while standing and sitting often stem from a lack of core or (as Paul “Coach” Wade would say) midsection strength. It’s also pretty common for people with weak midsections to have or develop back issues. Think of the midsection as a cylinder, if the “front half” isn’t doing its fair share, then the back half will be carrying an extra burden. If the abs aren’t able to hold us upright while standing or seated, then the back has to compensate that much more—often leading to discomfort or worse.

The great news is that instead of doing endless questionable crunches, the PCC and Convict Conditioning methodology emphasize training the midsection specifically, and instruct us to engage it when performing most (if not all) of the other calisthenics exercises. For example, It’s hard to even imagine performing a pistol squat without abdominal involvement—the same is true with any advanced push-up (it’s critical for Neuro-Grip push-ups)—and just about every other exercise in the PCC and Convict Conditioning curriculum.

While many different schools of training have their own approaches to counteracting the very modern problem of too much sitting, in this post I’ll mainly focus on calisthenics strength, and very basic mobility. Nothing too fancy is necessary for most of our general population clients to work on counteracting the dreaded desk body. But, if you are inclined to work more on mobility and flexibility alongside your calisthenics strength, definitely check out Al Kavadlo’s Stretching Your Boundaries.

I think of “un-desking” as having the following components:

  • Unlocking the hips and hip flexors
  • Abdominal/midsection strengthening
  • Stretching and strengthening the shoulders and upper back

Unlocking the Hips and Hip Flexors

The short bridge (also sometimes called the hip bridge or shoulder bridge) is a regular part of my mobility warm-ups and those I teach to others. It’s accessible for nearly anyone. When practicing the short bridge, the beginner is comfortable and in control as they work towards bringing the hips higher while engaging their glutes.

Start on the ground with your hands at your sides. Push down hard through your heels and strongly activate your glutes to get your hips as high as possible. This is nearly the opposite of slumping over at a desk. It’s sometimes helpful to think of pushing the hips up and over towards your head (but only THINK this, your feet need to stay on the ground).

Adrienne Harvey Short Bridge

The straight bridge is another extremely valuable early step toward a full bridge in Convict Conditioning that is very useful long after achieving a full bridge. Like the short bridge, you may also know it by other names. Those of use who spend a lot of time typing—and who are also pull-up enthusiasts can greatly benefit from this move. I love it and love to hate it. At the top of this bridge variation, be sure that the shoulders feel rotated back and down. Experiment with different hand positions (fingers facing forward, to the side, backwards) while working to bring your chest and body high off of the ground in a reverse plank position.

Adrienne Harvey Straight Bridge
Remember to try different hand positions when trying the straight bridge: fingers pointing towards the toes, out to the sides, or pointing backwards.

A favorite bodyweight stretch from the RKC curriculum also has great value for calisthenics practitioners. It’s no secret that I love kettlebells as much as I love calisthenics, and I’ve found that including this RKC hip flexor stretch in bodyweight only workout warm-ups can do wonders for bridging. If you find your hip flexors are tight and have never tried this drill before, give it a go! It’s a lifesaver after long car rides, or marathon writing sessions at the computer.

On a padded surface, get in a half-kneeling position. Without pushing forward in any kind of extreme lunge, simply think of tucking your tailbone while strongly activating your glutes. The front of your hip and thigh on the leg with the knee on the mat should feel a strong stretch. Take time with this powerful move and be sure to try it on both sides.

Abdominal/Midsection Strengthening

As mentioned earlier in this post, most if not all of the calisthenics exercises in the PCC curriculum and Convict Conditioning involve the abdominals. But if you or your students are having desk-related issues, focused abdominal strengthening can really help. The leg raise series beginning on the ground all the way up to the most exotic lever strongly impact the abs. Since the midsection recovers quickly, it can be trained much more often than most muscle groups—some may opt to train the midsection daily.

Adrienne Harvey Hanging Knee Raises
Double down on “un-desking” by combining slow and controlled hanging knee raises with a timed active hang. How slow can you go?

Stretching and Strengthening the Shoulders and Upper Back

Weak upper backs and weak shoulders tend to round forward during desk work—but so do the shoulders of active people—especially boxers and pull-up addicts! Spending time hanging from a pull-up bar can not only greatly increase grip strength, but it’s an opportunity to relax and activate the back with dead and active hangs—done for reps, this move is sometimes called a “scap-up” referring to the movement of the scapula. (In a past PCC blog post I outlined several different bar hang grips but in this case, even the most basic bar hang grip will fit the bill.)

Pay particular attention to how your shoulders and upper back are feeling, and if you’re a beginner, take it easy.

Adrienne Harvey Bar Hangs
The dead hang and active hang look and feel completely different!

Last but certainly not least, the Aussie pull-up, especially performed to the chest can help remind our shoulders to stay back where they belong. Far from being just a step on the way to the pull-up, the Aussie pull-up (aka bodyweight row) performed slowly with a nearly isometric hold at the top can help posture, upper back strength and lead to better lockouts at the top of standard pull-ups. Be sure to experiment with lower bars of various heights. The Aussie can be further regressed for beginners or deconditioned students by bending the knees. This shortens the lever of the body and places some of the body’s weight on the feet.

Adrienne Harvey Aussie Pullups, Bodyweight Rows

One of the great and occasionally frustrating things about progressive calisthenics is that there are so many options and there’s never time to talk about or do them all! I’ll just briefly mention dips here for intermediate folks, since the delightful chest stretch at the bottom of the dip (don’t dip so low as to risk impingement) is great after a day at the desk. Likewise a strong active hold at the top awakens many of the upper body muscles that suffer when we sit and slouch.

Adrienne Harvey Bodyweight Dips

Example Un-Desk Warm-Up Sequence (repeat for a few rounds if you have time):

Optimally begin by taking a short walk.

  • Short bridges: 5 reps, pausing for height and max tension at the top
  • RKC hip flexor stretch 1-2 per side
  • Dips and/or straight arm holds above dip bars
  • Bar hang alternating between dead hang and active hang (scap-ups) + a few pull-ups if they’re not maximum effort for you. This is not PR time.
  • Aussie pull-ups (aka bodyweight rows) 5 slow reps with max tension at top of each rep.
  • Short Bridge a few test reps to note improvement.

While it would be ideal for all workplace settings to have space for—and the social acceptance of—spontaneous exercise sessions, coming up with minimalist sequences for the work day can at least alleviate some of the issues until you can destroy the stress of the day at the gym or at home.

Bonus Slouch Slayer:

If you’re not sure if/when you’re slipping into a slouch at the desk, Place a mirror to the right or left of where you’re seated. While you work, take a second to catch a glimpse of your profile. Catching myself slouching a couple times was enough to build great upright posture habits at the desk. The moment you catch yourself in a really hunched slouch in that mirror, you’ll be motivated to sit up straighter, check your shoulders, abs, etc. At that point I’d also encourage you to stand up, and try a few of the calisthenics “un-desk” moves.

My home office is always a work in progress, but if I feel like I’m slumping, I’ll place that mirror to my left for a day or two – sure enough that fixes the problem!

Grip Strength for Greater Triumphs

September 6, 2016 By Adrienne Harvey 13 Comments

Adrienne Harvey Senior PCC Grip Training

Many times we associate grip strength and grip training with those ubiquitous spring-tension grippers and strongman training. While I really enjoy grip training with heavy odd objects, giant kettlebells, etc. it’s also very possible to train for a monster grip using bodyweight training only. With just a little creativity, bodyweight grip training presents infinite variations and challenges—and you can do most of it just about anywhere.

Having a strong grip is a prerequisite to so many bar-based calisthenics exercises—if you can’t hang on long enough, then you won’t be able to do a meaningful number of reps. Beginners will often need to build up their grip strength, as modern life and desk-based jobs don’t seem to test or build our grip.

As many PCC instructors and instructor candidates already know, grip strength is essential to passing the Century Test—you’ve got to be able to hang out on that bar for a while to do those twenty knee raises. In the excitement of testing, those twenty knee raises can seem to take a very long time, and you’ve got to hang on for every single one of them. Then, after the knee raises, the guys still need to do 10 pull-ups, and the ladies have to do their 10 Aussie pull-ups as well.

Convict Conditioning Vol. 2 remains one of my absolute favorites, and that’s not just because of the flags, it’s also the focus on grip training. The book begins with a comprehensive guide to hand and grip strength, and every time I look at it, it gives me more new ideas for training, some of which are presented below.

All Angles and Surfaces

At the PCC and in the Convict Conditioning book series, you’ll notice that there’s a variety of grips demonstrated—the “tactical” no-thumbs overhand grip most commonly seen on pull-ups, overhand with thumb wrapped, the chin-up grip with palms facing you, neutral grip with palms facing each other, wide grips, narrow grips, just a few fingers on each hand, two-arm, one-arm, finger-tip grips, and more.

Adrienne Harvey Bar Grip Training Collage
A few examples of the nearly infinite number of bodyweight grip training options.

Inspired by old time strongman training—which, properly scaled, is great for absolutely everyone—Paul Wade even includes adding a towel (and later two towels) to timed hangs for an extra challenge. A towel is hard to grip and hang from given its large diameter when bunched up, and because the hand is challenged in a less-familiar and surprisingly challenging vertical orientation.

One day, frustrated by the lack of a plain straight pull-up bar in a commercial gym, I came up with the following variation. I put one hand on one handle, but then looped a small hand towel around another one, then did a short set of 5-6 pull-ups. I made sure to switch sides every other set. It was a great grip challenge and can be done most anywhere.

I’m always looking for new places to do pull-ups. While my city is not constantly covered in scaffolding like NYC, I have been able to find great grip-challenging pull-up spots like I-beams, vertical rafters (very difficult, just doing short hangs there), open stairwell stairs, hand-only rope and pole climbs and more. The next time you visit a playground with young relatives, look around for grip challenge opportunities.

Chamber Press Neutral Grip
This is a favorite place to practice flag regressions like the chamber press. The “easier” neutral grip lets me focus on the rest of the movement.

One of my all-time favorite tips from Zach Even-Esh, author of The Encyclopedia of Underground Strength and Conditioning, is to vary the grip on each set of pull-ups (or push-ups) in a workout. Towards your last sets, you might be forced to get very creative.

Speaking of push-ups, if you haven’t tried, them, Neuro-Grip push-ups are a fantastic challenge of yet another angle of grip strength and training. I’ve found that the focus and strength required from them has helped with other exercises like dips, etc. on rings and even when performed on parallel dip bars.

Neuro-Grip push-upsYour Grip = Your Health?

Recent studies have found that grip strength is often an indicator of health. While it seems to be generally accepted that our grip strength declines as we get older, this is yet another opportunity to rebel against the mainstream. We can build up, increase, and maintain our grip strength into our later years if we keep training intelligently. Good health, grip strength and general strength will help us remain safe and independent in our senior years. That sounds good to me even now.

It Goes Both Ways: Train Your Extensors!

Adrienne Harvey Fingertip Pushups

Keeping our hands healthy means that it’s also important to “go the other way” too. In workouts which really emphasize grip training, I like to pair a grip intensive exercise with another exercise that either stretches or challenges the extensors—basically a superset. The extensor exercise can be something as simple as a well executed straight arm plank for time, push-ups, frog or crow stand, handstands if appropriate—or if you’re ready for it, you may want to experiment with fingertip straight arm planks or push-ups at this time too. There’s really no limit to the level of difficulty. It’s important to be patient and gentle though, as fingers seem to take a while to strengthen, and just a second to injure.

Here’s a sample combination from the last part of a favorite at-home workout:

  • 45 second pull-up bar straight arm hang
  • 30 second or longer crow stand
  • rest
  • 60 second pull-up bar straight arm hang
  • 45 second or longer crow stand
  • rest
  • 90 second (or keep going for a max PR) pull-up bar straight arm hang
  • 45-60 second straight arm plank

Grip Confidence and Breaking Through Mental Barriers

This last section might not apply to everyone, but I’ve observed both with myself and others that once we really begin to work on—and TRUST—our grip strength, then we’re often suddenly able to make a lot more progress on the skills which were otherwise right at the edge of our abilities. Getting the vertical chamber press and the next few human flag steps after it (human flag with one leg straight, one leg bent) were absolutely dependent on my confidence in my grip. I knew I had the strength, especially through the core, but in the past, kicking all the way up to vertical was fairly iffy. Turns out, my brain was putting the breaks on. Training my grip while still working on the rest of those progressions (but with a stall-bar-based neutral grip) was key. After finally putting the pieces back together, I’ve been able to reliably do the move on the first try and I’ve still been (slowly) progressing forward.

Is there a bar or vertical pole move that’s proved extra challenging for you? Could it be improved with a stronger grip and/or greater grip confidence?

The Centerline Principle of Strength & Power

April 26, 2016 By Matt Schifferle 20 Comments

Matt Schifferle Centerline

I first learned about the magic of the centerline principle in martial arts. Everything from powerful kicks to dodging punches involved moving in relation to the center of my body as well as the center of my opponent.

As it turns out, the centerline is not only the key to powerful kicks but also developing strength and muscle when applied to progressive calisthenics.

Technically, your body has 3 center lines, one for each plane of movement. The scope of this post is focusing on the centerline that divides your right and left side along the sagittal plane.

Each plane has its own centerline. This article focuses on the frontal plane centerline.
Each plane has its own centerline. This article focuses on the sagittal plane centerline.

Focusing on your centerline is critical towards your strength and muscle building efforts. It opens the door towards developing more muscle control as well as improved performance. It also greatly reduces stress around your joints. Even your balance and agility will greatly improve by directing your muscle tension towards your centerline.

MattSchifferleMusculardiagramThe image to the right shows how the muscles are arranged to direct muscle tension inwards towards the centerline. Almost every muscle has at least a few muscle fibers that direct force inwards towards the spine. This is yet another reason to practice back bridge progressions, as they develop all of the muscles in this image. While the bridge is classically described as a move for the posterior chain, it is also one of the best techniques for developing tension towards the centerline.

Knowing about the centerline is good, but it’s even more important to know how to use it in practical application. Below are three lessons on how to apply the centerline principle in your training.

 

Lesson #1: Avoid the “splat”

The centerline principal works because it encourages the tension in your muscles to converge between the right and left halves of your body. This serves as a powerful transfer of physical energy up against gravity.

You can find evidence of this even in nature, as anything that has been pushed up against the force of gravity is the result of two converging forces. A common example is the Rocky Mountains here in my home state, which were formed through converging forces deep within the earth pushing upward.

Converging forces push mountains up against the pull of gravity, just as they lift you up as well.
Converging forces push mountains up against the pull of gravity, just as they lift you up as well.

On the contrary, an object that does not have converging force holding it together eventually flattens out. A quick example is dropping a snowball or a glass bottle against a concrete sidewalk. As gravity pulls against the object and it meets an unyielding surface, the matter of the object spreads outwards. This is what I call the “splat effect” and it can happen to your body anytime you are working against gravity.

Gravity causes objects to spread out against the ground or floor. In this push up, I have to use my chest muscles to keep my elbows from spreading outwards.

Through directing your muscle tension towards your centerline you gain stability and muscle control so you can more effectively drive yourself up against the pull of gravity.

 

Lesson #2: Progressively apply force closer to your centerline

Many of the progressions in Convict Conditioning involve moving the hands and feet closer together. Close push-ups and squats are a great example of this. When you employ this style of progression you are putting force in a more direct perpendicular line against gravity. This brings you a host of benefits including greater flexibility, balance, muscle control plus more range of motion in the joints. It also forces you to be stronger since you are pushing your centerline in the most direct vector against gravity for the greatest distance possible.

Going narrow in grip or stance is a great way to make use of the centerline principle.
Going narrow in grip or stance is a great way to make use of the centerline principle.

It’s important to understand that simply pulling your hands or feet closer to your centerline is only part of the progression. You also want to pull your elbows and knees closer in as well. To a certain degree, you can even pull your shoulders and hips in slightly. I like to think of trying to make myself as narrow as possible. This helps me draw myself inward sort of like a guy sucking in his gut on the beach, only now I’m pulling myself in sideways as opposed to front to back.

 

MattSchifferleScrewLimbsInwardLesson #3: “Screw” your limbs inwards

Many of the muscles in the legs and arms “wrap” around your body’s bones and joints, sort of like stripes on a candy cane. Even muscles that look like they run straight up and down the limb have an origin and insertion point that is slightly offset from one another. The reason for this is to partially create inward torque along the limb as you move about. This inward torque is very important for creating that converging force within the body when doing unilateral movement such as throwing a ball or taking a step.

Screwing in your limbs is a little counter intuitive at first because your arms and legs torque in opposite directions to one another. Your right arm and left leg torque in clockwise while your left arm and right leg torque counterclockwise. It’s sort of confusing at first, so I just keep in mind that the knees and elbows both torque inwards. The knees torque in towards your centerline as they bend in front of you, while your elbows toque inwards as they bend behind you.

As the elbows torque in or out the tension in the back follows towards or away from the centerline.
As the elbows torque in or out the tension in the back follows towards or away from the centerline.

It’s important to note that torquing your legs inwards doesn’t mean your knees cave inwards. When your torque is applied there should be very little lateral movement in both the knees and the elbows. This is why I refer to applying limb torque as “locking up” the limb. It makes it stiff and stable just like twisting a towel makes it stiffer.

MattSchifferleTowel1

Lock it up! Applying torque on your legs or arms will make them more stable. Lock it up! Applying torque on your legs or arms will make them more stable.

If you can apply all three of these centerline lessons you’ll quickly discover more strength, stability, and power than you’ve had before. More importantly, your strength will become more functional and you’ll prevent joint stress that will erode your health and vitality. Just like any aspect of progressive calisthenics, using the centerline principle takes time and practice, so be patient with it. Also, look for opportunities to apply it even if it doesn’t impact the moving limbs. You’ll be amazed at how torquing in your arms can improve abdominal activation with hanging knee raises. Keeping your hands together is also a great way to make narrow and single leg squats more challenging.

Best of luck with your training and let me know if you have any questions down below in the comments!

Strength Rules Is Here

November 24, 2015 By Danny Kavadlo 24 Comments

Danny Kavadlo Strength Rules Book Cover

First Things First

I am the luckiest guy who ever lived. When my last Dragon Door title, Diamond-Cut Abs was released one year ago, it was extremely well received. In fact, it became a #1 bestseller!

Diamond Cut Abs Bestseller

I consider it a tremendous honor that my words, programs and experiences resonated with so many. I am grateful that in the months that followed, I received a great deal of correspondence about Danny-style abdominal training. But, interestingly enough, for as many abs-related questions and comments as I received, there were even more inquiries about Danny-style strength training as it relates to the entire body. People loved the abs, but they wanted more! In fact, I had never authored a book about full-body strength training… until now!

I knew I had something unique to bring to the table and here it is… Strength Rules.

Full Disclosure

Just prior to the writing of Strength Rules, my life went through some unprecedented and unexpected changes. Things that I thought would last forever fell apart. On New Year’s Day 2015, a ten-year relationship with the woman I thought I would spend the rest of my life with ended. Fast.

Things change. I’ve never needed strength more than I have in the past year. I went from being a family man to a full time single dad. I had to be strong for myself, but even more so, for my son. It was at this time when I realized that a book about full body physical strength simply would not be enough…. My next work would have to be about mental strength, spiritual awareness and emotional fortitude as well.

Danny Kavadlo Truth

So There You Have It

Strength Rules is my most personal work to date. The project is about perseverance, endurance and overcoming obstacles. It contains over seventy-five bodyweight exercises, including Plyo-Muscle-Ups deconstructed like you’ve never seen before, not to mention my in depth take on One-Arm Push-Ups. This book is about working hard and mindful practice–making the time to train, prioritizing what matters most and not taking “No” for an answer. We cover living a healthy life, harvesting physical prowess and fostering a positive mental attitude. Strength Rules focuses on walking face-first through the fire, and coming out stronger for it. Not in spite of it, but because of it!

Danny Kavadlo Muscle-Up

Everything is fair game in these pages and I pull no punches. Be prepared not only for my unconventional take on nutrition, but also on the supplement businesses, equipment manufacturers and even the medical industry!

Danny Doc

Further, Strength Rules contains workouts, progressions, supplemental stretches and some amazing (and far out) images. It even has the long awaited return of Danny’s Dos and Don’ts! I can’t wait for you to check it out!

But Don’t Take My Word For It

In the words of Olympian, scholar and author Dan John (from the foreword):

“This book is about true strength. The old kind of strength where heroes were people, like Beowulf and Ullysses, who protected the community first. This book is about empowering yourself and others. Strength Rules by Danny Kavadlo is so good you can’t ignore it.”

Danny And Wilson
Strong to the finish.
