Hey all, happy new year first off. I've run into some hip flexor pain when I do squats. I'm 5'8" 165, I would say 8% bf. I squat 315x2, 275x8. My right hip flexor especially gets sore/ is always tender and I squat every tuesday, 135x15, 185x10, 225x10, 275x8, then 225 for reps for 2 sets. I omit the 315 as of late until I can get the 275 for 10. Even if I do a squat motion my hip flexors hurt, not enough to stop me but its annoying. I go parallel with all my weight, past with light weight. Should I do more stretchting prior to the squats? I only wrap my knees at 275+ and its not super tight.
