What is one benefit to measure your body's flexibility?

a. meeting the national requirement for flexibility
b. determining your muscular strength
c. tracking your flexibility improvements over time
d. increasing the length of your life

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.

yes. i think it is for sure.
