L.I.F.T.

Chris at Conditioning Research posted a great entry about the different benefits of squatting and deadlifting.

What really caught my attention was this quote from Matt Metzgar, taken from a post on his blog:

“Toddlers squat constantly, but it is all “mobility” work. The squats are done for the purposes of movement, not for the purposes of lifting a weight. If a toddler wants to lift a weight, they shift into a deadlift position.”

The Back Squat

As far as squatting goes, there are a ton of squatting types/forms.  What the authors above are talking about is a natural full-squat position, similar to the resting/seated position used by most people in most “undeveloped” countries:

The exercise called “the back squat” involves placing a bar across your upper back, and squatting with it.  As the authors mention (and Mike Boyle harps on), this can cause injury if proper form isn’t maintained – that is, if you progress too fast in weight.

The body is only as strong as its weakest link, and, in most “modern” people the lower back is a very weak link.  When you put that weight on your shoulders, and squat down, if your mobility sucks, you bend forward, and all of that weight goes to your weak link.

Then the weak link breaks.

The “back squat” though, is called the “back squat” not just because you put the weight on your back, but because it is a back exercise.  The back squat, traditionally, was thought of more as a strengthener of the back than of the legs.  The deadlift, as the authors above mention as well, was traditionally a leg exercise – though not even the “predominant” leg exercise…that was the “front squat.”

The Front Squat

The front squat involves supporting a bar across the front of your shoulders, and squatting with the weight held there.

The front squat usually allows for a much greater range of motion than the back squat, because the weight is ahead of the individual.  It also uses the quadriceps much more than the back squat, and can take a lot of the loading off of the lower back, as the back is necessarily kept in a more upright position (to avoid falling over).

This is the squat used in Olympic lifting, where lifters frequently achieve weights in excess of 3 or 4 times their bodyweight.  And it uses the “full squat” (“mobility”) position.

The Deadlift

The deadlift was called “The Health Lift” by most writers before 1970.  It was considered the single best lift for achieving total body strength.  I think it still is.

However, the deadlift has its own problems, which are, or can be, very similar to those encountered in the back squat.

If form is sacrificed in the traditional deadlift, and the lumbar spine rounds, the load, again, is transferred to that spot, and the weakest link goes.

The Goal – Maximal Strength within Proper Technique

The problem with all of these discussions is that they try to make a claim that one exercise is “better” than another.  That “better” can mean “builds more strength,” or “is less dangerous,” or “has a higher functional carryover.”

But there is no absolute truth…except, maybe, this:

If you do any exercise with proper technique, to the current limit at which you can sustain proper technique, and progress as you are able, you will be fine.

No exercise is “better” than any other.  They’re all good.  They all have their time and place.

The problem happens when people try to rush things, and sacrifice technique for “success.”

Sacrificing technique for success = failure.

Write that on your whiteboard.
