Unlike other products, this is a great characteristic to let you determine if you can even go through with the program. Of the various fitness test practices involved with the program, there is one that is implied to maximize your heart rate.

This heart rate test requires that you perform jumping jacks nonstop at a quick and steady pace for two minutes.
