<h3>Answer: </h3><h2>Tracking your flexibility improvements over time</h2><h3>Explanation: </h3>
There is no apparatus for measuring body's flexibility, as this factor is something that an individual feels by looking at the changed posture and performance. The benefit that one gets from looking at one self is of tracking his/her own rate of flexibility over a period of time and see improvements and changes themselves.
One Benefit is that you can track your progress. Flexibility is so important because it helps reduce the risk of hurting yourself. For example, if you were to kick your leg really high, if you are not flexible and/or stretched out, you could possibly tear a muscle.
In a game of tennis, the match starts with "love" or zero and goes up to 40. From love, it goes 15, 30, 40, then game point. Deuce refers to when the game is tied.
