Hyperextending the legs on a leg press machine involves straightening the
legs beyond their natural range of motion, which places excessive stress
on the knee joint and surrounding structures. This can lead to injury or
damage to the ligaments, tendons, cartilage, and bones of the knee. The
knee joint is designed to function within a specific range of motion, and
hyperextension can cause the joint to become misaligned and unstable,
increasing the risk of injury. Additionally, hyperextension can also put
unnecessary stress on the lower back, leading to back pain or injury.
Therefore, it is important to avoid hyperextending the legs while using a
leg press machine and to use proper form and technique to ensure a safe
and effective workout.
