5. Hip Flexor Stretch
To effectively stretch the hip flexors, first, kneel on your right knee, with toes down, and place your left foot flat on the floor in front of you.
Place both hands on your left thigh and press your hips forward until you feel a good stretch in the hip flexors.
Contract your abdominals and slightly tilt your pelvis back while keeping your chin parallel to the floor. Hold this pose for 20 to 30 seconds, and then switch sides.
Tip: To accentuate this stretch, reach your hands over your head and arch your body back.
