As far as I remember I had problem hyperextending my lower back in exercises like back squat and deadlift. The problem starts with very low weights so lately I just did some auxiliary exercises instead of main lifts (cable one leg deadlifts with row as preached by Dean Somerset, step ups). I know that stretching quads and hip flexors along with glutes and ab work should help so for now I do just that (anterior pelvic tilt)…
What else ca I do? Any specific auxiliary exercises (mainly to improve my DL, SQ is less of a problem)? How can I practice DL to improve my form in regards to this?
