Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Position yourself at the top of a pull-up bar using a box or step. Grip the bar with a shoulder-width, overhand grip. Engage your core and maintain a straight body. Slowly lower yourself for 3-5 seconds until arms are fully extended. Step back onto the box and repeat.
Control the descent for maximum muscle engagement. Keep shoulders down and back. Use a box/step for comfortable starting position. Breathe steadily, exhaling during the descent. Start with fewer reps and increase gradually.
Muscle Train is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
