Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Feet wider than hips, kettlebell between feet. Core tight/flat back, hip hinge/soft knees to grab handle top. Explode hips/knees straight to clean to chest (hands to horns, elbows in)—rack position. Squat hinge (thighs parallel or mobility limit, straight back/chest up). Drive mid-foot to stand. Repeat.
Master bodyweight squats first. Rack tight: Chest level, straight wrists/elbows in (lat engagement). Wristband for rack pressure comfort. Slow eccentric, bottom pause, smooth up. Full-foot balance (no heel/toe bias).
