Planet Fitness Age Policy

Planet Fitness has specific age rules for membership and gym access. You must meet certain requirements to join or bring minors, and parental consent is necessary for younger teens.
Minimum Age Requirement for Membership
You must be at least 18 years old to sign up for a Planet Fitness membership on your own. If you are between 13 and 17 years old, you can join, but only with a parent or legal guardian’s permission.
Those under 13 cannot have membership or enter the gym independently. This rule is consistent across most locations due to safety and liability concerns.
Your age must be verified during sign-up, and you are typically required to provide valid ID to prove you meet the minimum age requirements.
Rules for Minors Accompanied by Adults
If you are under 18, you cannot visit Planet Fitness alone. Children aged 13 to 17 must be accompanied by a parent or guardian whenever they enter the facility.
You cannot bring younger children, such as a 5- or 11-year-old, into the gym even if you have a membership. They must remain outside or in supervised areas if allowed by that specific location.
Some franchises may have additional restrictions on minors, including requiring adult supervision at all times while in the gym. Always check local rules before bringing anyone under 18 with you.
Identification and Parental Consent
When signing up as a minor (13-17 years old), you will need to provide identification such as a birth certificate or state ID to verify your age.
Parental or legal guardian consent is mandatory. The parent must be present during the registration to provide permission and may need to co-sign the membership agreement.
This process ensures your guardians are fully aware and approve of your membership, complying with liability and safety policies at Planet Fitness. You may also need to complete waivers or agreements relating to gym use.

Alternatives for 12 Year Olds Interested in Fitness

If your 12 year old cannot use Planet Fitness facilities, there are other practical options to support their physical activity and health goals. These alternatives provide age-appropriate environments and programs that encourage fitness safely.
Youth Fitness Programs
Youth fitness programs are designed specifically for children and teens. They offer supervised workouts, often combining strength, cardio, and flexibility exercises tailored to young bodies. These programs prioritize proper technique and gradual progression to reduce injury risk.
Many programs include group classes, personal training, or sport-specific conditioning led by certified trainers. Your child can benefit from social interaction while staying motivated. Equipment and routines are adjusted for their age, making these programs safer than adult gyms.
You can find youth programs at specialized fitness centers or community sports organizations. Some gyms offer separate youth memberships with strict supervision, but minimum age requirements usually start at 13, making dedicated youth programs a better choice for 12 year olds.
Community Recreation Centers
Community recreation centers provide a variety of physical activities for kids in a controlled, safe setting. These centers often have gyms, swimming pools, and courts for basketball, volleyball, and other sports that promote fitness.
Many offer structured classes such as dance, martial arts, and swimming lessons, which develop endurance, coordination, and strength. They also host open gym times where you can encourage your child to be active under supervision.
You typically need to register your child and provide proof of age. Some centers require parental supervision or participation during certain activities. Recreation centers emphasize fun and skill development rather than competitive fitness, making them well suited for younger children.
