Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Sit on a bench edge, hands gripping for support. Feet flat, knees bent 90 degrees. (Optional) Have a partner add weight to your lap. Slide hips off the bench, extending arms. Lower until elbows are at 90 degrees. Press through palms to return to start. Repeat with control.
Keep elbows pointing back. Engage your core. Avoid elbow lockout. Start light, focus on form. Controlled tempo, no bouncing. Inhale on lower, exhale on push.
