The elbow-to-foot lunge is a lengthening exercise that promotes flexibility and mobility throughout the hips and hamstrings.
Stand tall with your feet shoulder-width apart and your arms hanging at your sides.
Lunge forward with one leg, keeping your shin perpendicular to the floor, and place your opposite hand on the ground so that it is even with your front foot. Bend your other elbow to 90 degrees and reach it towards the floor, placing it inside your front shin. Return to the standing position.
Do not push the stretch past your point of comfort.
