Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Start with feet shoulder-width apart, arms at sides. Initiate a quarter squat, pushing hips back. Swing arms back to generate momentum. Jump forward explosively, swinging arms forward and extending legs. Land softly on the balls of your feet, knees bent. Reset and repeat.
Use arm swing for momentum. Engage your core for stability. Bend knees for a soft landing. Maintain chest up, look forward. Start with shorter jumps to refine technique.
