Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Sit on the Captain’s Chair, back against the backrest. Grip handles for stability. Legs hang freely. Engage your core. Slowly lift knees towards chest, controlled. Pause at the top, contracting abs. Lower legs slowly, without swinging. Repeat.
Maintain slow, controlled movements. Avoid leg swinging; focus on core engagement. Keep back pressed against the backrest. Exhale on knee lift, inhale on descent. Start with moderate reps, increasing as strength improves. Reduce range of motion if lower back discomfort occurs.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
