Change of Support (Posture) Drill: Back Against the WallÂ
Video by Nuno Costa
As we continue to focus on your ideal position, we are now going to use the wall to assist us in finding and maintaining the Figure 4 position. We want you to do this drill with your heels about 1-2 inches away from the wall, with your back to the wall. Establish your ideal position from here and now we want you to change support from one foot to the other. Having our backs to the wall prevents us from kicking the leg back (think butt kick) and this will be pertinent for when we are running. We want you stay as close as possible to the ideal position; if your foot is behind the hip joint, you are slightly out of position. From there you will have to engage your hip flexors to pull the trail leg back to the ideal position.
