Introduction: What “Family of 4” really means at gyms For most gyms, “family” refers to two adults in the same household plus dependent children (often up to age 22–26 and living at home). But policies vary by brand and location:

• Budget chains typically don’t sell a single family plan; each person signs up individually, or one adult plan can bring one guest per visit.
• Full-service and premium clubs may allow you to add a second adult and “junior”/child add-ons to one account.
• Community centers (YMCA, JCC, parks & rec) commonly offer true family memberships with youth programming and childcare.
