Gym Builder
What it is
Gym Builder is a self-hosted, web-based WordPress plugin for managing fitness classes, trainers, members, and memberships. Its free core provides weekly timetables with per-slot capacity, automatic booking, and seat counts. Unlimited membership packages can use class-based tiers and tabbed pricing tables. The plugin creates WordPress member accounts, emails credentials, and provides ID cards and front-end dashboards. Included calculators cover BMI, body fat, water intake, and protein intake. Paid add-ons add Stripe checkout, recurring or one-time billing, subscriptions, and a member self-service portal. Other integrations include WooCommerce, Google Calendar and Meet, Zoom, Elementor, and Gutenberg. Fitness tracking supports workout programs, logs, body measurements, goals, progress charts, and member-trainer chat. The Pro AI Agent offers around 40 admin-only abilities, works with OpenAI, Anthropic, or Google, and requests confirmation before destructive actions. Pro page tools include nine Gutenberg blocks, 17 Elementor widgets, and six niche templates. The Pro Bundle costs $59.99 a year, billed yearly.
