The Centerline Principle of Strength & Power

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.

MattSchifferleMusculardiagram The 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.

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.

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.

Lesson #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.

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!

A Karate Approach to Calisthenics

June 2, 2015 By Owen Johnston 15 Comments

Back of the Wrist Pushups

Like many of my generation, I grew up watching movies like The Karate Kid, Kickboxer, Enter the Dragon, Drunken Master, and Rocky. The larger-than-life characters from these films wowed us with their fighting skills and never-give-up attitudes.

A common theme they all share is that the main character is an underdog who must train hard to become a better fighter and overcome his seemingly invincible opponents. The training methods employed often include some tough calisthenics skills. I’m sure we all remember seeing Rocky do uneven pull-ups in the second film, and dragon flags in the fourth. The perseverance of our heroes, the amazing skills they learned, and the rigorous training methods they endured inspired many of us to take up martial arts and training ourselves.

Bruce Lee popularized the dragon flag as well as other difficult bodyweight feats, like his two finger push-ups. He espoused improving your athletic performance in order to improve your martial performance, as well as to help fully express the human body. Certainly, the martial-calisthenics connection is as old as man, yet Bruce was a great catalyst in the popularization of martial arts in America, inspiring many to train hard like he did. He said, “Life is never stagnation. It is constant movement…as well as constant change. Things live by moving and gain strength as they go.”

I didn’t fully understand the implications of these words until I got into Progressive Calisthenics. There are certainly comparisons to be made between learning progressive calisthenics and martial arts. Coach Wade made some of these comparisons in “The Tao of PCC”. He brought up some important similarities to martial arts. “…nobody can remember a hundred techniques in a fight. What matters are the principles you absorb.” “You learn the form, you absorb the form, you discard the form.”

Our training shouldn’t keep us stuck in a rigid form, but instead be directed to the fullest expression of ourselves with utmost efficiency and simplicity. In Jackie Chan’s older films, many of his characters often went through a transformation from a struggling student to a graceful, efficient and powerful athlete. The training was generally harsh, but once he absorbed the principles of his master’s art, he was ready to face the next challenge!

Like the progressive calisthenics approach, traditional power training and body conditioning methods in Okinawan karate focus on bulletproofing the joints, improving flexibility, and building holistic, functional strength.

One Arm One Leg Fingertip Training

There are a number of progressive bodyweight movements taught in Okinawan karate, including knuckle push-ups, fingertip push-ups and ultimately, wrist push-up variations. The exercises have very direct benefits for “bunkai” or application of kata.

Of course, these exercises shouldn’t replace previous progressions, but supplement them. Also, don’t overdo it with directly training the joints. Be sure to allow plenty of time for your connective tissues to adapt.

To regress any of these variations, you can practice them using an incline (wall, chair etc) or you can simply create less demanding leverage by kneeling instead of performing them from your toes. You could also adapt the Convict Conditioning push-up progression to these variations. (Coach Wade has already covered this for fingertip push-ups in Convict Conditioning 2.)

Warm up your hands and forearms properly before working knuckle, fingertip or wrist push-ups. Afterwards, shake your hands out, and stretch your fingers and wrists.

Like most push-up variations, knuckle push-ups strengthen most of the muscles used in straight punches. Knuckle push-ups also strengthen the wrists and knuckles, and help toughen up the skin. A course of fingertip push-ups, grip work, pull-ups, and proper use of a heavy bag will help you punch as hard as Rocky Balboa!

Fingertip push-ups strengthen the finger extensor muscles. Naturally, they provide direct benefits to strikes using extended fingers. Fingertip push-ups can be progressed by doing push-ups on fewer fingers.

The author, Owen Johnston demonstrates a push-up on just the index fingers and thumbs.

Wrist push-ups strengthen the wrists for various strikes, and have very specific benefits for “ox jaw” and “crane” techniques. This push-up variation is done on the backs of the hands. You can also ease in by having one palm on the training surface instead of having both on the backs of the hands. Practice this way on both sides to maintain symmetry in training.

Wrist Stretches by Owen Johnston, PCC Instructor

A stretch commonly done in gymnastics will be useful in preparing for a wrist push-up progression. Sit in a kneeling position, look straight down at your knees, lean forward slightly and place the back of your hands on the ground, directly in front of your knees. Naturally, leaning forward will put some of your weight onto the backs of your hands, with the fingers turned inward. Cautiously lean into your hands until you feel mild discomfort. Hold this stretch for 10-30 seconds, then come up and shake your hands out. Repeat 1-3 times.

There are “hidden steps” between this stretch and a wrist hold in the top position of a kneeling push-up. First, gradually build strength and flexibility in the wrists with the stretch until you can put moderate pressure onto the backs of your hands with little to no discomfort. The next part of the progression is to move your hands a few inches forward from the starting position and unfold your hips slightly as you start putting pressure on the backs of your hands. Imagine that you are trying to move a little closer to perfect form for push-ups (hips locked out, weight carried through arms and hands). Find the most difficult position that you can hold for 10-15 seconds when you put mild to moderate pressure on your hands. Gradually work towards the full kneeling push-up wrist hold.

A sample progression:
1. Wall wrist push-ups
2. Incline wrist push-ups with one palm on contact surface and the back of the other hand on contact surface
3. Incline wrist push-ups
4. Kneeling wrist push-ups with same regression as in step 2
5. Kneeling wrist push-ups
6. Hold top of push-up position on backs of hands; use same regression as in steps 2 if needed at first
7. Full push-up with one palm on contact surface and back of other hand on contact surface
8. Full wrist push-ups

Programming and volume for wrist pushups are straightforward. Since the joints don’t adapt as quickly as the muscles, and the wrists can tend to be injury prone, be conservative about volume. Practicing wrist push-ups once a week for low sets of low reps is a good rule.

A few options for programming wrist training:
1) Adding it to an existing joint specialization session; see Convict Conditioning 2 for a template
2) Doing some wrist stretches, holds and/or pushups as part of your warm-ups for practice (whether karate or a sport that needs strong hands/wrists)
3) Doing some light stretches and other exercises as part of rehabilitating your wrists (of course, this will depend on what exercises your physician recommends)
4) Training wrist holds after a session of pushups
5) There are many other possibilities depending on your own needs, goals, experience, etc.

Back Of Wrist Push up variations

Martial arts and calisthenics can work hand-in-hand to develop all of the qualities needed for the development of strength and technique. I hope that you, dear reader, find my examples of this to be clear and useful. The Okinawan martial arts and the methods that Coach Wade wrote about are ancient, but are still around because they work, and can work well together!

The Tao of PCC by Paul Wade

March 12, 2013 By Paul "Coach" Wade 57 Comments

I am the man who wrote the book, Convict Conditioning. I am not a perfect man, and my book is not a perfect book; but I hope that when people judge the book, they will say that it got much more right than it got wrong.

They certainly couldn’t say that about the man.

Without improving, evolving, moving forwards, we are nothing. There is no standing still in life—you are either moving forward, or you are losing ground. That’s why I was so excited to be able to contribute to PCC. There is no doubt in my mind that PCC will do for bodyweight training what the RKC has done for kettlebells. And that would be incredible.

A lot of folks have asked me how PCC will be different from Convict Conditioning. I can sum that up in one word: KAVADLO. Al Kavadlo is, for my money, the greatest progressive bodyweight training coach on earth. PCC, as a total system, is much bigger than Convict Conditioning alone because it has been expanded by Al’s methods, tools and tactics. His “new-school” has met my “old-school”, and PCC is the result. PCC is as much Al’s baby as mine—maybe more so. It is flat out false to assume that the PCC is just a “Convict Conditioning cert”. People who love Convict Conditioning will love PCC, because Convict Conditioning forms just a part of PCC. But PCC is more than just Convict Conditioning.

Much more!

PCC: A Black Belt in Bodyweight

Perhaps the most important difference between PCC and Convict Conditioning is the fact that PCC is about principles, not techniques. Convict Conditioning is very easy for athletes to pick up and understand, because it presents six groups of ten techniques. PCC goes deeper than this. Anyone who has ever studied a martial art knows that they need to learn scores of techniques to achieve a black belt; but the closer you get to true mastery, the more you come to understand that it’s not the techniques that matter—nobody can remember a hundred techniques in a fight. What matters are the principles you absorb.

PCC is like this; you will drill and explore dozens of key techniques at the cert workshop; and the PCC Instructor’s Manual analyzes and illustrates over one-hundred and fifty exercises! But at the heart of PCC are the principles of bodyweight progression. Once you grasp these principles, you can make any calisthenics exercise progressive: from a rehab level, right up to epic Bruce Lee-level bad-assery. This is what it’s all about. Some people have accused Convict Conditioning of being too dogmatic; too rigid. Nobody could say the same about PCC, because it’s based on principles, not set exercises paired with progression standards. There is so much more flexibility built in.

Though they play an important role in the early stage, the techniques should not be too mechanical, complex or restrictive. If we cling blindly to them, we shall eventually become bound by their limitations. —Bruce Lee

The punches and kicks—the 14 chains

A martial artist seeks to absorb principles, but he or she can only absorb the general by accumulating the specific—lots and lots of individual punches, kicks, throws, etc. The road to calisthenics mastery ain’t no different. Bodyweight athletes still need to learn individual techniques. They still need to learn about chains—i.e., technical progression sequences. It’s important to note that the fundamental movement-types in Convict Conditioning are all still present in the PCC system; however they have been expanded and added to. The seven fundamental movement chains in PCC are:

1. Push-ups—building to—one-arm push-ups

2. Pull-ups—building to—one-arm pull-ups

3. Handstand push-ups—building to—full handstand push-ups (between chairs)

4. Horizontal pull-ups—building to—“torquers” (one-arm, one-leg Australian pull-ups)

5. Dips—building up to—strict muscle-ups

6. Leg-raises—building to—strict rollovers

7. Squats—building to—wushu pistols

Anyone who knows Convict Conditioning well will see that all the major movements are here (save bridges, which I’ll address in a sec). Two new movement chains have been added to the system; the first is the horizontal pull-up. The basic form of this exercise will be well (and painfully) known by Convict Conditioning exponents, but here the progressions have been jacked up to an advanced level to add more symmetry to upper-body work (the vertical handstand push-ups and vertical pull-ups are antagonistic opposites; now the horizontal push-up has an antagonistic “buddy” in the horizontal pull-up). Complete dip progressions—missing from CC—have also been included, with these culminating in one of the most popular of Al’s bar moves: the uber-cool muscle-up (known as a sentry pull-up to CCers).

al_blacknwhite

The muscle-up—part pull-up, part dip—is an advanced technique in the PCC dipping chain.

Where CC progressions can still be found in the PCC system, they are often approached differently, thanks to Al’s input. For example hanging straight leg raises are real popular in jails: but we got the feedback from athletes on the outside that they were just too easy. So we have expanded and advanced the progressions, making the advanced techniques much, much harder. One-leg squats have also been made harder. Everything is at a higher turn of the spiral. More progression options have been included for pull-ups and push-ups. Extra handstand pushups variations have been included.

As I have said, the PCC system is much larger than Convict Conditioning. Convict Conditioning is really about building raw muscle and motive power by utilizing fairly basic, fairly brutal, pulling, pushing and leg movements. But bodyweight strength training is about more than that—static holds, for example. Whereas Convict Conditioning didn’t include full progressions for static holds, PCC does. The system includes 7 static chains:

1. Press holds—building to—the elbow lever

2. Midsection holds—building to—the L-hold

3. Bridge holds—building to—the gecko bridge

4. Handstands—building to—the frog-press handstand

5. The back lever—building to—the full back lever

6. The front lever—building to—the full front lever

7. The side lever—building to—the press flag

That’s a pretty damn impressive roll-call of techniques: and very few men or women outside of professional gymnastics could complete all seven. Fewer still could assimilate or teach chains for all seven. But this knowledge is part of the PCC system thanks to Al’s know-how, and has been integrated into PCC because I’ve been asked so often about these holds; athletes want to learn about old school hand-balancing, flags, elbow levers, and so on. Fans of bridges wanted to know how I would include them as a form of static hold. All this is contained in the PCC system. This doesn’t mean you can’t begin using these “holds” as “moves”—levering up from a bridge into a handstand, for example. Remember, everything is about principles, not dogma. Once you understand how to work with the techniques, you can expand; you can explore. You learn the form, you absorb the form, you discard the form.

A bodyweight powerhouse, Al Kavadlo is no stranger to static holds. Perfection!

The PCC Instructor’s Manual will cover all 14 chains in-depth (it’s over 600 pages), but it will only be available to athletes who attend the PCC event. The certification workshop itself cannot cover all 14 chains—over 150 exercises—but it has been painstakingly designed to cover the key techniques, training methods, and the principles behind progression.

The eleven training modules and two seminars over the three-day workshop will revolutionize you: no matter what your level of development. Sure, you may not come away able to perform expert hand-balancing, elbow levers, front-levers, one-arm pull-ups and human flags, but I promise you this: you WILL come away knowing exactly how to get there—or get someone else there—in the best way possible.

Ralph Waldo Emerson—the great Patriot, and possibly the greatest essayist of all time—said this:

As to methods there may be a million and then some, but principles are few. The man who grasps principles can successfully select his own methods. The man who tries methods, ignoring principles, is sure to have trouble.

Come and join us in the PCC community. The principles you need to maximize your bodyweight potential are waiting here for you.
