The cable posas raise is one of the most underrated lower body movements in the game. Tight hip flexors and weak hip flexors are so common when we see back pain and knee pain. This is a fundamental movement to include at the end of a hard leg day to keep you pain-free
This is like my favorite low back pain relief. Most people with low back pain have a tough time for breathing into the abs and low back so they have suboptimal bracing. This decompresses the spine while helpfing create these pattern.
Squats and Hip Flexors do not mix. There is no relationship. They hate each other. The only way to target your hip flexors is with loaded hip flexion. Loaded hip extension is all glutes.
