Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart, resistance band under your feet. Hold band ends at shoulder height, palms forward. Engage core, maintain upright posture. Press arms overhead, fully extending elbows. Pause briefly, arms straight (not locked). Slowly lower to starting position. Repeat.
Maintain neutral wrists, aligned with forearms. Keep shoulders down and back. Control movement throughout. Adjust grip/resistance if shoulder discomfort arises. Exhale on press, inhale on lower. Start with lighter resistance to refine form.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
