Aqua Aerobics - Jumping Jack

Jumping jack may be easy on land, but in water, you would need to work again water resistance. In short, double the effort you have to do it on land. Give it a try and you will realise that it isn't as easy as it seems.

In this video, this exercise is done without the "noodle" (long cylinder float). When include "noodle" for working the arm in this exercise, one will face greater water resistance.
