Do not hyperextend legs on a leg press machine. Straightening legs
excessively stresses the knee joint, risking injury to ligaments, tendons,
cartilage, and bones. The knee joint is meant for a specific range of
motion, and hyperextension can destabilize it, elevating injury risk. It
also strains the lower back, causing pain or injury. Avoid hyperextension;
maintain proper form and technique for a safe and effective workout on the
leg press machine.
