The Banded Hip Flexor Stretch is an effective exercise for stretching the hip flexor muscles. To perform this stretch, attach one end of a thick band to a post at hip height and insert your leg into the band, bringing it up to your hip. Step back to create tension in the band, then kneel down on the banded knee. Maintain a neutral pelvis and engage your glutes. Lean forward into the stretch for 5 seconds, return to the starting kneeling position, and repeat this motion 5-8 times. Switch to the other leg and repeat the exercise to promote flexibility and relieve tightness in the hip flexors.
