Strong inner thighs help stabilize the hips and knees and keep the feet and knees pointed forward during a run.
- To work your left inner thigh, lie down on your left side. Keep your core engaged, and press your left elbow and forearm onto the ground, directly under your left shoulder. If this feels uncomfortable, you can modify the exercise by lying all the way down and resting your head on your left arm.
- Bend your top (right) leg, and place your foot on the mat in front of you.
- Extend your left leg as straight as possible, then lift it up off of the ground just a few inches, before lowering it back down. Try to focus on lifting your leg from the inner thigh muscles in order to avoid using your hip flexor or swinging your leg up.
- Keep your core engaged, and try to keep your right hip stacked directly over your left as you move. Lift and lower your left leg 20 to 30 times, then switch sides and repeat.
