I've decided that the weakest part of my squat is the initial drive from the bottom. I would like to work on increasing my range of motion (this is an ongoing process.) So the easiest thing to do is try and work on increasing power when the hip is flexed. Don't know too many ways to do this.
Does anyone have suggestions? All I've come up with is overloading the bar at depth and practicing it isometrically, then dropping the bar incrementally (or putting plates under the feet). Better suggestions are welcome. Are there any isolation exercises that work the glutes specifically? I feel like I am doing way too much with my quads which I think is what is limiting me. If I go really deep, I get pain in the quadriceps tendon, not the knee.
(The form looks very good, but I suspect that how the forces are moving through me are a bit off. Correct me if I am wrong, but the hip drive starts from the glutes and the quads assist on the way up. The lower I go, the squishier this feels = glutes not working well, even though most people would claim it looks great.)
Thanks in Advance!
