Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Grip parallel dip bars inward, shoulder-width. Jump up to support weight. Keep body straight (no lean, legs hanging). Lower slowly eyes forward to elbow=shoulder height. Press up without arm lockout. Repeat.
Don't lower too far (shoulder strain risk). Focus on triceps: Squeeze at top, feel stretch down. No elbow lockout. Slow rep timing for max results.
