Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Adjust the machine so knees align with the pivot point. Sit with a straight back and feet flat. Place knees inside the levers, keeping them together. Grip handles for stability. Exhale and push knees apart, engaging hip abductors. Pause briefly at the widest point, feeling muscle tension. Inhale and slowly return to the starting position. Repeat.
Maintain a neutral spine. Focus on hip muscle engagement, not feet or legs. Control movement throughout. Start with lighter resistance. Avoid knee lockout. Breathe steadily: exhale on exertion, inhale on return.
