Planet Fitness has a new challenge to help teens stay in shape this summer, and earn some scholarship dollars as well.

Starting on May 15 and running through September 1, high school students between the ages of 15 and 18 can work out as much as they want at over 1,700 Planet Fitness locations through the U.S. and Canada, as part of the 'Teen Summer Challenge Scholarship Sweepstakes.'

All they must do is visit any Planet Fitness location with their parent or legal guardian and register for free the promotion.

But in addition to the challenge, the company is giving away a total of $30,500 in scholarships. More than 50 teens will be randomly selected to receive a $500 scholarship and one grand prize winner, selected at random, will receive a $5,000 scholarship.
