Keene's Planet Fitness

Planet Fitness moved into the Monadnock Marketplace in Keene in 2015.

Planet Fitness is offering free workouts to teenagers ages 15 to 18 at any of its locations from May 15 through Sept. 1, as part of its nationwide Teen Summer Challenge.

Last summer’s pilot program in New Hampshire saw more than 2,500 teens log nearly 12,000 gym visits at the state’s 18 Planet Fitness locations.

All teens who sign up are automatically entered into Planet Fitness’ scholarship sweepstakes. By the end of summer, 51 teens across all 50 states and Washington, D.C., will be randomly selected to receive a scholarship toward academics or athletics, including one $5,000 grand prize. Teens will also have the chance to win prizes on Planet Fitness’ Twitter and Instagram channels throughout the summer, such as club swag, movie tickets and wireless headphones.

Interested teens may sign up at Planet Fitness in Keene’s Monadnock Marketplace. Teens under 18 must be accompanied by a parent/guardian at sign-up.
