Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Release the safety handles and stand with legs straight. Lower heels for a deep calf stretch. Drive through the balls of your feet to raise heels as high as possible, squeezing your calves. Lower under control to the starting position.
Actively drive through your big toes to maximize calf engagement and stability during the lift. Control the lowering phase (negative) to maintain tension and prevent momentum, focusing on a slow and deliberate descent. Ensure a full stretch at the bottom of the movement, feeling the calf muscles lengthen, but avoid pushing beyond your comfortable range. Maintain a static knee position throughout the exercise to isolate the calf muscles and prevent unwanted movement.
