Odin Fitness

Odin is a progressive bodyweight training app that requires zero equipment. Designed for people who want to build strength and muscle anywhere -- hotel rooms, small apartments, parks, or while traveling -- Odin is suitable for complete beginners through advanced practitioners, with progressive difficulty scaling. Unlike gym-based apps, Odin is built specifically for bodyweight-only training with no equipment upsells, and features offline mode and gamified progression. Odin is free to start, with a paid premium tier available.
