Which stretch is typically not recommended for non-athletes due to the risk of injury?

Ballistic or dynamic stretching involves using momentum to force a muscle to stretch beyond its normal range of motion. This type of stretching is characterized by quick, bouncing movements that can increase the risk of muscle strains or joint injuries, particularly for non-athletes who may not have the conditioning or flexibility to perform these movements safely. The rapid nature of ballistic stretches can result in overstretching, leading to potential injuries.

On the other hand, static stretching involves gradually elongating a muscle to a comfortable position and holding it there, which is generally safer for non-athletes. PNF stretching, while more advanced and potentially beneficial for increasing flexibility, also requires a partner and careful execution, making it less accessible for the general population. Active stretching involves moving parts of the body through a full range of motion, which, while safer than ballistic stretching, may still lead to strain if not performed properly by those without an adequate fitness background. Therefore, ballistic/dynamic stretching is less advisable for non-athletes due to its higher injury risk.
