THIS WEEK'S QUESTION
From our video "Go Home, Get Weak, and DIE" | Why Your Doctor is WRONG about Lifting Weights (click the title to watch):
Peter
I'm confused. Various of the lifters seemed to be lifting in a wrong way. I realise that suggests that my 'take' on this must be wrong. I'm not seeing 'bend the knees' lifting?
Phil
Reasonable question Peter, and what you're probably referring to is a very conscious decision to not only bend at the knees (so the knees do indeed bend of course), but also bend the hips, i.e., bend over as one lifts. In the squat, this makes for a stronger movement (as opposed to trying to keep the back angle vertical), and it's also easier to achieve depth. In the deadlift, this makes it possible to make sure that the knees are not an obstacle for the bar's path (when the knees get in the way of the bar, it makes for a very difficult, inefficient, and weak deadlift).
Note, however, that although the back goes through a host of angles - from vertical at the top of the movement to relatively horizontal at the bottom of the movement - we still want a straight back. And indeed, this is exactly how the back gets stronger. The muscles of the back (and the entire trunk) are responsible for keeping the back flat and rigid - like a steel beam - throughout the entire movement. And so one begins at a very manageable weight at which one can maintain the correct positioning and movement, the body adapts to that weight by getting stronger, and then we increase the weight slightly, and the process begins again.
Here's a solid explanation in this video we put out a few weeks back:
