Element 5 Fitness is offering a free 8-week body challenge to anyone that wants to come sweat it out for a great cause.

The challenge begins Sept. 20 and includes an Element 5-style bootcamp workout. Top participants that make the biggest transformation will win prizes, donated by local businesses.

The challenge is free, with a $10 suggested donation that will benefit Charity Water. The non-profit organization brings clean, safe drinking water to people in developing nations.
