Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand between parallel bars facing forward. Grip bars shoulder-width, palms down. Arms straight, lift feet off ground by bending knees to chest. Pause at top, squeeze abs. Slowly lower legs to start, keep core engaged throughout.
Firm shoulder-width grip on bars. Engage core (pull belly button to spine). Stay straight, no swinging/momentum. Exhale up to chest, contract abs; hold 1 sec. Inhale, lower slowly/controlled. Prioritize form over reps.
