I've been doing the Starting Strength program lately and have been feeling great with it.
My only question is one concerning the squat. Mainly, I'm wondering if I'm crouching down far enough. I definitely feel it in my legs but sometimes I do have to "correct" myself (perhaps my upper body leaning to far forward...) with a brief muscle contraction in the lower back which doesn't hurt but does make me wonder if I am performing the exercise correctly.
Here's what I do: the bar is across my back and a bend my knees until my upper leg and lower leg (with regards to the knee) form a 90 degree angle - slightly before reaching parallelism. So I'm not going down really far but I am feeling it right in the quads and it's tough work to get back up.
I've looked into the "proper" method but it appears to be variable - while people may be doing the squat, it looks as if there are different methods in which to perform it. I've also run into a term which implies an action, if I am understanding it correctly, that I do not do in my squat. The phrase is "Ass to the grass". I've gathered that this means that you should squat low enough so that your hamstrings come into contact with your calves. Again, this is not something I do nor is it something I come close to doing. Should I?
I want to correct this, if it needs correcting in the first place, before I go on much farther with the training program even if it means removing weight so that next week I can begin working out with the best possible form and progress from there.
