Flexibility, when defined, is the range of motions at a certain joint, or else said, the speed it can move from one point to the other. It gives quality, precision and definition to every move. As a result, we get to be more functional in our everyday chores.
Flexibility is mostly needed to make us perform each type of activity with ease. Sedentary lifestyle or even the wrong type of activity can make flexibility to deteriorate. This can lead to different health issues such as joint problems, obesity, injuries while training etc.
