Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Feet shoulder-width apart, knees slightly bent. Hold a slam ball in front. Engage core, extend arms to lift ball overhead, rising onto toes. Slam the ball forcefully, using your core and arms. Catch or retrieve the ball. Return to start.
Maintain a straight back and engaged core. Choose a challenging but manageable weight. Generate power with your whole body, not just your arms. Exhale during the slam, inhale during the lift. Start slowly to master technique.
