Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Anchor band low behind you. Face away, handles at shoulders. Step forward for tension. Stance hip-to-shoulder width, soft knees. Press overhead to full elbow extension. Pause, lower controlled. Adjust with band strength/combos.
Step far enough for full tension. Control descent—no snapping. Elbows front (not flared wide). Neutral spine: Glutes/core engaged. Build resistance gradually for form.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
