You might be doing this hip flexor stretch wrong! If you’re focusing on driving the hips forward and not tucking your pelvis under your body, the hip flexors aren’t getting the stretch you want. Not to mention, you’re also reinforcing a bad position for your low back.
This is a useful stretch for a lot of people, but especially is your job requires a lot of sitting. It’s great for warm ups or anytime throughout the day to keep your back from getting sore. Give it a shot and let us know how it goes.
Move well. Eat clean. Be happy.
