Planet Fitness membership is generally available to anyone 13 years of age or older. However, members under 18 must follow additional rules involving parental consent, supervision and club access.
Teenagers between the ages of 13 and 17 must have a parent or legal guardian present when joining. The parent or guardian must sign the membership agreement and a legal waiver giving the minor permission to use the club.
Members who are 13 or 14 years old must be accompanied by a parent or guardian at all times while using the gym. Planet Fitness does not provide childcare, and children cannot be left unattended while a parent or guardian works out.

What Is the Minimum Age to Join Planet Fitness?
The minimum age to become a Planet Fitness member is generally 13 years old.
Children under the age of 13 cannot purchase a standard Planet Fitness membership or use the gym as an unsupervised member.
Teenagers who meet the minimum-age requirement must still follow the rules established for minors.
Can a 13-Year-Old Join Planet Fitness?
Yes. A 13-year-old may join Planet Fitness with the involvement and permission of a parent or legal guardian.
At the time of joining:
- The parent or guardian must be present.
- The parent or guardian must sign the membership agreement.
- The parent or guardian must sign a legal waiver.
- The waiver must give the minor permission to use the club.
- The minor must be accompanied by the parent or guardian whenever using the gym.
A 13-year-old cannot be dropped off and left alone inside the club.
Can a 14-Year-Old Work Out at Planet Fitness?
A 14-year-old may become a member, but the member must be accompanied by a parent or guardian at all times.
The supervising adult must remain with the minor while the minor is inside the club.
The parent or guardian must generally be either:
- A Planet Fitness member, or
- The Black Card guest of the minor member
Families should ask their local club how this rule is applied before purchasing a membership.
Can a 15-Year-Old Go to Planet Fitness Alone?
Members between the ages of 15 and 17 must have a parent or guardian present when signing up.
The parent or guardian must:
- Approve the membership
- Sign the membership agreement
- Sign the legal waiver
- Give the teenager permission to use the club
The rules provided specifically require continuous adult supervision for members ages 13 and 14. However, individual clubs may have additional policies for older minors, so a 15-, 16- or 17-year-old should confirm whether independent visits are permitted at the selected location.
Planet Fitness Rules for Members Ages 13 to 17
Teen members must follow the same club rules as adult members, along with additional age-related requirements.
These rules include:
- The minor must be at least 13 years old.
- A parent or guardian must be present when the minor joins.
- A parent or guardian must sign the membership agreement.
- A legal waiver must be completed.
- Members ages 13 and 14 require continuous adult supervision.
- Children may not be left unattended inside the club.
- Planet Fitness does not provide childcare.
- Local club rules must be followed.
Parents should explain gym etiquette, safe equipment use and appropriate workout limits before allowing a teenager to exercise.
Parent or Guardian Consent Requirements
A person between the ages of 13 and 17 cannot complete the membership process independently.
The parent or legal guardian must be present during enrollment and sign the required documents.
These documents may include:
- Membership agreement
- Liability waiver
- Consent to use the club
- Billing authorization when the parent is paying
- Other location-specific forms
The signed waiver confirms that the parent or guardian permits the minor to participate in gym activities.
Rules for Members Ages 13 and 14
Planet Fitness applies stricter supervision requirements to its youngest members.
A member who is 13 or 14 must be accompanied by a parent or guardian at all times.
This means the adult should not simply:
- Drop the minor off at the entrance
- Wait outside in a vehicle
- Leave the club during the workout
- Ask another minor to supervise
- Leave the child unattended while exercising elsewhere
The supervising parent or guardian must remain inside the club and be responsible for the minor.
Does the Parent Need a Planet Fitness Membership?
For members ages 13 and 14, the parent or guardian must generally be either a Planet Fitness member or attend as the Black Card guest of the minor member.
Because membership structures and guest-access procedures can vary, parents should ask the club how the adult’s access will work.
Questions to ask include:
- Does the parent need a separate membership?
- Can the parent enter as a Black Card guest?
- Must the same guardian attend each visit?
- Can another legal guardian supervise the minor?
- Does the adult need to remain next to the minor during the entire workout?
Does Planet Fitness Offer Childcare?
No. Planet Fitness does not provide childcare services.
Parents cannot leave babies, young children or other minors unattended at the club while they exercise.
Planet Fitness gyms are fitness facilities rather than childcare centers, and employees are not responsible for supervising members’ children.
Parents who need childcare must arrange care outside the gym before beginning their workout.
Can Children Wait Inside While a Parent Works Out?
Children and minors who are not eligible members should not be left unattended inside Planet Fitness while a parent or guardian works out.
This includes waiting in areas such as:
- The lobby
- Seating areas
- Locker rooms
- Hallways
- Entrance areas
- Other parts of the club
A child cannot be left under the informal supervision of Planet Fitness employees.
Why Does Planet Fitness Have Age Restrictions?
Age requirements help protect young members and support safe use of exercise equipment.
Gym equipment can present risks when used incorrectly, including:
- Improper lifting technique
- Excessive weight
- Falls
- Strains and sprains
- Equipment-related injuries
- Overtraining
- Dehydration
Parental consent and supervision help ensure that younger members understand club rules and use the facility responsibly.
What Should Teenagers Bring When Joining?
A teen and parent or guardian may need to provide:
- Proof of the teenager’s age
- Parent or guardian identification
- Contact information
- Payment or billing information
- Emergency contact details
- Signed membership agreement
- Signed legal waiver
The exact documents required may differ by club.
Calling the location before visiting can prevent delays during enrollment.
Can Teenagers Use All Planet Fitness Equipment?
Teen members may be able to use standard gym equipment, but access can depend on:
- Their age
- Club policy
- Safety considerations
- Equipment instructions
- Parent or guardian supervision
- Additional program rules
Teenagers should begin with manageable resistance levels and learn the correct form before increasing weight.
They should also follow posted rules and staff instructions.
Can Teenagers Use Black Card Amenities?
Access to Black Card amenities may depend on the teenager’s membership, age and local club policy.
Some amenities may have separate safety or age requirements.
Parents should ask whether a minor can use features such as:
- Massage chairs
- HydroMassage
- Tanning services
- Red-light or wellness equipment
- Guest privileges
- Other Black Card areas
Legal age restrictions may apply to certain services, especially tanning.
Can a Minor Be a Black Card Guest?
Guest eligibility can depend on the club’s current Black Card policies and the guest’s age.
A parent or guardian should confirm:
- The minimum guest age
- Whether a waiver is required
- Whether the Black Card member must remain present
- Whether a minor guest can use all equipment
- Whether certain amenities are restricted
Do not assume that guest access follows the same rules as a full teen membership.
Planet Fitness High School Summer Pass
Planet Fitness has offered teen-focused summer access programs at participating locations in previous years.
When available, these programs may allow eligible teenagers to work out during a specified promotional period.
Program dates, eligibility rules, parental consent requirements and participating locations may change each year.
Families should check the current Planet Fitness website or contact their local club for details about any active teen summer program.
