Wondering if you guys had any advice for this one. I can't seem to make any inroads on my hip flexibility despite my constant stretching and foam rolling. Every day it seems to snap back to its previously inflexible state. I thought it might be a lack of specific muscle strength that's causing it but I'm not sure. Any suggestions on exercises? I'm currently just doing a hip flexor stretch where you kneel in a lunge position and tilt to the opposite side. That and the one where you lie on your back and bring the knee towards the chest.
