The Problem: Weak hip flexors.
How I think I know this: When I hit parallel with “challenging” weight, I feel a twinge in my hips and my hips pretty much collapse causing the lift to fail.
Ruled out knees, because I can do lunges with heavy weights.
Ruled out posterior chain, because I can deadlift “challenging” weights.
I have been working really hard on my squats the past 18 months, but once the weights get heavy, my hips give out.
Analyzing the problem, I realized that I wasn’t held enough as a child and that is the real cause of this weakness/imbalance. Actually, this hip flexor weakness probably has plagued me my entire life - I was never fast off the line, while lateral movement is/was no problem.
The Solution (this is where I need your help obviously): I have been doing the following -
On squat day-
5 x 5 as heavy as I can go to almost parallel.
5 x 5 atg as heavy as I can handle (about half of the heavy sets)
Band Good mornings
Band Pull throughs
On deadlift day-
I’d really appreciate any insights or suggestions you might have to strenghten my hip flexors.
