Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Squat, keeping your chest up. Jump vertically, extending hips, knees, and ankles fully. Land softly on the balls of your feet and immediately repeat.
To minimize impact, bend your knees and hips as you land, absorbing the force through your legs and allowing your arms to naturally counterbalance the movement. Focus on driving powerfully through your feet to generate maximum upward momentum, engaging your glutes and quads for a forceful jump. Maintain an upright posture with your chest lifted to engage your core and prevent rounding of the back. Push your knees outward, tracking over your toes, to improve stability and activate your inner thigh muscles. Explode upwards by forcefully contracting your leg muscles, focusing on a powerful hip extension to propel yourself vertically.
