Teenagers ages 15 - 18 can visit any Planet Fitness location in the United States and Canada. Online signups are not available. Teens under 18 must bring a parent/guardian to sign up. Once the parent/guardian waiver is signed for teens under 18, teens can workout alone. Students who are already 18 do not need a parent or guardian to be present during the sign-up process.
In 1993, the Grondahl brothers hired Chris Rondeau, Planet Fitness’ current CEO, to work the front desk. Rondeau and the Grondahls recognized that there was a greater opportunity to serve a much larger segment of the population if they changed the gym environment, both in attitude and format, by creating a non-intimidating, low-cost model. Planet Fitness then became known as the "Judgement Free Zone," aimed more at the average user than the bodybuilder type of fitness enthusiast. As early as March 2015, the "Judgement Free Zone" policy has been expanded to allow trans women to use the women's locker room. The policy states that "members and guests may use all gym facilities based on their sincere self-reported gender identity."
