I have a few problems concerning my squat form...
- my lower back rounds when I get below parallel. If I don't get below parallel I can't generate as much power
-when I try a wide stance, as I squat to the bottom, the hip flexors want to pull my legs and knees back together, even though I try to push out with the knees
question is how can I improve my form, any type of training, that will help those issues? esp the back rounding one? thanks
