How to: Position yourself on your hands and knees, in tabletop position. Engage your abs engaged by pulling your belly button in towards your spine (a). Keeping your hips pointed towards the ground and leg bent to a 90-degree angle, raise your left knee out to the side as high as you can (b). Pause at the top, then return to starting position (c). Repeat, then switch legs.
The hip rotators not only rotate the thigh on the pelvis but more functionally rotate the pelvis on the weight bearing fixed thigh. Activities such as swing a golf club, and even just walking require some rotation of the pelvis on the weight bearing leg. While we don't need that much range of motion to walk, activities such as running, dancing, tennis, and many other sports can require more hip rotation.
How to: Lie on your back with your right knee bent and foot flat on the floor (a). Extend your left leg up to the ceiling and wrap a strap around the sole of your left foot (b). While holding both ends with your left hand, extend your right arm directly out to the side in order to anchor yourself (c). Slowly let the left leg fall toward the left while keeping your right side grounded. Hold for six to eight breaths, then repeat on the opposite side.
To avoid hip flexor pain, you should pay more attention to these muscles, Dr. Siegrist explains. When you are seated, your knees are bent and your hip muscles are flexed and often tighten up or become shortened. “Because we spend so much of our time in a seated position with the hip flexed, the hip flexor has the potential to shorten up. Then, when you are in a hurry because you are running to catch a bus or a plane, or you trip and fall, the muscle could become stretched. Here’s this stiff, brittle muscle that all of a sudden gets extended, and you could set yourself up for strain or some hip flexor pain.” Click Here to Learn Unlock Hip Flexors
