What should one aim to stretch the muscle to when improving flexibility?

When aiming to improve flexibility, the goal is to stretch the muscle to about 10% beyond its normal length. This target allows for a safe and effective increase in flexibility without risking injury. Stretching beyond this point can lead to strain or damage to the muscle and surrounding tissues, as the threshold for elasticity of muscles is limited.

Stretching to this recommended level ensures that the muscle fibers can adapt and lengthen safely, promoting better range of motion and reducing the likelihood of tearing or overstressing the muscle. This principle is foundational in physical education and athletic training, as it focuses on enhancing performance while maintaining the integrity of the body’s musculoskeletal system.
