Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Start prone, legs extended, feet together. Hands under shoulders, palms down. Engage core, press through palms to lift chest and extend arms, keeping elbows close. Arch back and lift head. Briefly hold, then slowly lower.
Keep elbows close to your body. Control movements for muscle activation and injury prevention. Engage your core for stability. Exhale on the push up, inhale on the lower.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
