Yes, overstretching can be detrimental.
Overstretching is problematic because it can compromise joint stability. Connective tissues, such as ligaments and tendons, play a crucial role in stabilizing joints. When these tissues are excessively stretched, they can lose their ability to properly support the joint. This leads to increased and uncontrolled joint movement, which, in turn, can cause tissue breakdown and ultimately, injury. Therefore, while stretching is important for flexibility, exceeding the safe range can be harmful.
