It is generally thought that a supple body leads to better physical performance and prevention of injury, but the idea of “the more flexible, the better” does not always seem feasible. Being flexible means having a large joint range of motion, with muscles and tendons that can be stretched more easily. However, experts say that, given the nature of muscle tissue and the structural vulnerability of joints, having large flexibility is not necessarily a good thing. Nevertheless, flexibility is a component of physical fitness and efforts to increase it are required in any kind of exercise, therefore we need to carry out body conditioning exercises using stretches appropriate to our objectives.
