Stand facing a plate-loaded lever calf machine and place the balls of your feet on the foot platform with heels hanging off. Press up gently to stretch the calf muscles, then lower your heels in a slow, controlled motion until you feel a deep stretch in the back of your lower legs. Keep your core braced and avoid bouncing to maintain tension and improve flexibility.
Log your lever calf stretch plate loaded sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
