The straight-leg calf stretch improves the flexibility of the lower leg and mobility around the ankle.
In a staggered stance, stand about two to three feet in front of a wall. Make sure the toes of the back foot are about even with the heel of your front foot.
Place your hands against the wall, lean against it, and shift your weight to the back foot until you feel a stretch in the calf muscle of your back leg. Hold for 30 seconds, relax, and return to the starting position.
Avoid bending the stretched leg. Make sure to keep it straight during the stretch.
Keep the stretched leg heel grounded. Do not let your heel come off of the ground during the stretch.
