We met Dr. Richard Ulm at the 2015 Arnold Sports Festival. We were dashing around from spot to spot shooting video for Barbell Shrugged. Richard, an expert on weightlifting and rehabilitation, was keeping himself busy putting blown-out athletes back together. It took a few months but we’ve finally gotten around to sharing some of Dr. Ulm’s unique insight and knowledge here on the DAILY. Enjoy, geek out and implement. You’ll be stronger! 

 

I have the opportunity to speak all across the country on weightlifting and rehabilitation, and I am often asked,“When should I use a belt”? What I am not asked – the far more important question – is “HOW should I use a belt”?

I’m always surprised to encounter athletes, even high-level weightlifters and powerlifters, who don’t know how to use their belt properly. That’s a shame because these are powerful and beneficial training tools. What’s more, encountering athletes capable of maximizing the utility and carryover of the weightlifting belt is even more rare.

To fully understand how to use a belt, we need to discuss how the body stabilizes for movement. The term core is often thrown around in gyms and rehab clinics all over the country, but it is rarely understood. To keep it simple, the ‘core’ is comprised of three structures that attach to the spine and pelvis – diaphragm, abdominal wall and pelvic floor. Together these structures form a functional pressure cooker of sorts.

The lid of the pressure cooker is the diaphragm, a dome-shaped muscle attaching to the spine and the ribcage which separates the chest cavity from the abdominal cavity. The wall of the functional pressure cooker is the abdominal wall made up of the transverse abdominus, external oblique and internal oblique. These structures function like a corset wrapping around the abdomen and connect the pelvis to the ribcage.

The bottom of this pressure cooker is the pelvic floor which is made up of a web of muscles attaching the sacrum (tail bone) to the innominates (funky-looking bones which are your hip bone, your pubic bone and your butt bone all in one) holding the pelvis together.

Because all of these structures are contractile, they have the ability to expand and contract to control the volume within the abdominal cavity. If we have control over the volume of the abdominal cavity, we have control over the pressure (Ideal gas law – PV=nRT). Pressure within the abdomen (IAP) is THE foundation of all movement and is what using a belt is all about.

Here’s how it works.

The diaphragm concentrically contracts pulling the central tendon down towards the pelvis. As the central tendon descends, the contents within the abdomen press against the pelvic floor and outward into the abdominal wall. If the abdominal wall expands, the volume of the abdominal cavity does not change, which means the pressure remains constant. If, however, more pressure is necessary to execute the task (say you are cleaning 100K), then the abdominal wall will contract, resisting this outward-pushing force to decrease the volume of the abdominal cavity.

Because pressure and volume are inversely related, the smaller the volume of the abdominal cavity, the greater the pressure within this cavity.

What is indispensable in this process (and yet often overlooked) is the outward-pushing force created by contraction of the diaphragm. This outward-pushing force is the keystone of all movement. Proper usage of a belt is all about maximizing the magnitude of this outward- pushing force (IAP) to increase the stability of the spine during strenuous tasks like maxing out in the deadlift.

What a belt does is replace the abdominal wall in the stabilization process. It is stronger, and stiffer, enabling us to generate more IAP because it can resist a greater magnitude of this outward-pushing force. The greater the force within the abdominal cavity, the greater the pressure pushing the spine against the belt, squeezing it and locking it in place.

When you are using a belt, you need to consciously maximize pressure within the abdomen, not just “tighten up” like most athletes do. This is accomplished by concentrically contracting the diaphragm to increase the force pushing outward into the abdominal wall — as opposed to outdated and yet prevalent strategies which involve drawing the stomach inward.

Drawing the stomach inward does activate the abdominal wall, but not the diaphragm and it certainly does not increase IAP to any significant degree. What needs to happen is the diaphragm needs to contract and the pelvic floor and abdominal wall need to eccentrically activate to resist the outward-pushing force created by the descending diaphragm. Here, we have maximal activation of the entire abdominal pressure cooker instead of just the abdominal wall.

To generate an optimal amount of IAP (whether with or without a belt), the diaphragm must be parallel to the pelvic floor. In this posture, the ribs are down and the spine and pelvis are in a neutral position. With this parallel relation, the diaphragm and pelvic floor are able to oppose each other to maximize the magnitude of this outward-pushing force. What is important to note here, and where virtually everyone messes up, is that this outward-pushing force must push equally in all directions, not just forward. This is referred to as circumferential activation of the abdominal wall because it activates the full circumference of the abdominal corset.

Most athletes do not (cannot) circumferentially activate their abdominal wall because they overuse their spinal erectors to stabilize which hyper-extends their lumbar spine and tilts the pelvis forward, pulling the diaphragm, abdominal wall and pelvic floor out of centration. This is called the extension/compression stabilizing strategy and is pervasive in sports, especially Crossfit.

A common cue that perpetuates this problem is “push your belly into the belt.” This is a decent cue, but more often than not, the athlete will inadvertently turn on their spinal erectors, arch their lumbar spine and push their belly forwards into the belt. What needs to happen is the athlete needs to be able to push their lateral and posterior abdomen into the belt without losing a neutral position of the spine.

For most athletes, this is actually very difficult. Some of the cues that I find helpful are “push your spine into the belt” and “try to break the belt by pushing your sides into it.” Both of these cues will get the athlete to generate a lot of IAP and will teach them to circumferentially activate the abdominal wall instead of hyper activating their spinal erectors.

A very effective drill to teach this concept is to roll up a small hand towel so it is about 2” in diameter and place it vertically between the belt and the spine and then have the athlete feel the pressure in the abdomen pushing the spine backwards, crushing the towel between the spine and the belt. What is extremely difficult is maintaining a tall, neutral spine.

Most athletes will want to crunch forward which puts their spine in a flexed position (not good) and does not increase the pressure within the abdomen to any significant degree. To avoid this, I will often have the athlete get tall, place my hand on the top of their head and have them crush the towel without losing their head’s contact with my hand. This is a powerful drill because it teaches the athlete to stabilize with IAP, to circumferentially activate the abdominal wall, and to maintain a neutral spine. If you can get your athlete to do this, you can get them to use a belt properly.

So what do we need to remember?

  1. Proper stabilization is all about maximizing generation of IAP.
  2. IAP is generated by the abdominal wall and pelvic floor resisting the OUTWARD-pushing force created by concentric contraction of the diaphragm, NOT by sucking/drawing the abdomen in.
  3. Athletes need to activate the full circumference of the abdominal wall (especially the back, which is rather difficult).
  4. Since it is so common for athletes to overuse their erectors and only push their belly’s forward into the belt, it is important that the athletes can stay tall and crush their spine between the IAP and the belt.

Belts are useful and even necessary tools of the trade that, when used properly, can keep an athlete healthy and push their PRs to new heights. Unfortunately, using a belt properly is more difficult than many realize. Hopefully this clears up some confusion and you all can go out, lift more, lift longer, and lift smarter.

This article is a great starting point, but there’s still far more to discuss. For more, you can check out my site, Athlete Enhancement. You can also follow me on Twitter and Facebook.

Now, go break in your belt!

    Nice read! I’m always curious as to how tight I should tell my athletes to make the belt. I understand the point is to increase intra abdominal pressure to a substantial degree but how tight is too tight? Just curious if you have a tip for that or is it more of a preference. Thanks!

      too tight is very bad. You shouldn’t be squeezing he stomach inward. You should tighten down on it, but still retain the ability to push outwards.

      Being able to push out at all angles into the belt is the key.

    I have found much success with my belt and it appears that I have been lucky enough to incorporate proper mechanics while doing so. My question is; belt placement and how it varies between lifts ie dead lifts to back squats. Is it a matter of comfort or are there optimal placement suggestions.

    Thanks, Love you stuff btw!

      I tend to wear my belt a little higher up the belly when I pull, but this is largely a preference thing. If you move it around and feel like you’re in better pulling position, that’s a good thing. Adjust during sub-maximal sets and see what feels best.

    Awesome article! Thanks for all of the information. Only one thing.

    My stomach should not be modeled as an ideal gas… 😛

    What do we do if we have had inguinal hernia surgeries before and are worried about increasing our IAP too much causing another hernia?
