Stand on the foot platform of a lever calf raise machine with the shoulder pads or lever resting comfortably on your shoulders. Position the balls of your feet on the edge of the platform with heels hanging off. Raise your heels by pressing down through the balls of your feet, contracting your calf muscles at the top. Slowly lower your heels below the platform level to feel a stretch, then repeat with controlled movement for effective calf strengthening.
Log your lever standing calf raise sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
