Planet Fitness is home of the "Judgement Free Zone" which means they don't cater to body builders or power lifters. Planet Fitness strives to provide a relax, comfortable, non-intimidating atmosphere where everyone can work at their own personal goals.
In fact, if you grunt or drop your weights, the Planet Fitness Lunk™ Alarm will sound off reminding you of their non-intimidating atmosphere.
Planet Fitness also does not have any salespeople -- just friendly staff readily available to help you if and when you need them!
