Test your Muscle Strength*


Did you know that our muscle mass and strength peaks at age 401 before declining at accelerated rate? One can lose up to 8% muscle mass per decade2. Additionally, muscle strength loss occurs 2 times faster than muscle mass loss every year3.

Muscle Loss is preventable & reversible4. While muscle loss is a natural part of the aging process, with timely intervention of the right exercise and nutrition solutions, we have the ability to keep our muscle and strength at their peak.


How Strong Are You?
