The inner thighs can become incredibly sore, especially on longer runs, so do this stretch to target that area. Stand with your feet wide enough so you can place your hands on the floor in front of you. If you can’t reach, rest your hands on a bench or step. Inch your feet as far away from each other as you can without feeling any pain, and while keeping the soles of your feet pressed firmly into the floor. Keep your hands resting on the ground for support, or if you get down far enough, rest your shoulders on the floor and reach your hands through your legs. Relax here for 30 seconds.
