Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Adjust the seat so knees align with the machine's pivot point. Sit back, feet under the padded bar, resting above ankles. Grip handles for stability. Extend legs fully, exhaling, back pressed against the backrest. Pause briefly at full extension. Slowly lower the weight, inhaling, maintaining control. Repeat.
Align knees with the pivot point. Control movements for muscle engagement and injury prevention. Avoid knee lockout. Engage quadriceps, not momentum. Maintain a neutral spine against the backrest. Start with lighter weight to refine form.
