Hi, I'm Natalie Jill. Let's talk about how hip flexors play a role in your squats. What many people may not realize is that if they have very tight hip flexors, their squat form is not going to be correct and that is what's going to lead to lower back pain. It can absolutely lead to lower back pain. The best way to stretch your hip flexor is to down on your knee, have one base leg planted in the front. Your other leg is resting behind you on your knee and you're going to slowly rock forward to stretch that hip flexor. You're not going to be in line with your spine, posture is straight, but you're really going deep into that hip flexor. Tight hip flexors can prevent the proper squat form by causing an excessive forward lean. This excessive forward lean places undue stress on the lower back. If you have tight hip flexors, you can and should absolutely stretch and foam roll them before squatting to improve your posture and technique.
