Why can't a person hyperflex their limbs?

Answer 1

Hyperflexion of limbs, which involves bending joints beyond their normal range of motion, is typically limited by anatomical structures such as ligaments, tendons, and joint capsules that provide stability and support. Most people's flexibility is constrained by these structures, as well as muscle tension and protective reflexes that prevent injury. While some individuals may exhibit hypermobility or increased flexibility, excessive hyperflexion can lead to joint damage, pain, and instability. Thus, the body's design inherently limits the extent to which limbs can be hyperflexed to maintain overall joint health.
