Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Seated on a bench with your feet elevated, hold a bar across your thighs. Engage your calves and lift your heels to raise the bar, pausing briefly at the peak. Slowly lower the weight back down while keeping your core tight and maintaining constant tension in your calf muscles.
Maintain an upright posture throughout the movement. Focus on driving upwards through the balls of your feet. Engage your core for stability and to protect your lower back. Pause at the highest point to maximize the calf contraction. Control the descent to keep tension on the muscles.
