2026 Selection Criteria
What We Evaluate

Top 5 AI Workout Program Apps 2026
1. Smart Rabbit - The Free Champion
Score: 9.5/10
Smart Rabbit revolutionizes the market in 2026 with a unique approach: a 3000+ line expert system encoded in Claude AI, created by a state-certified coach and 4th place WNBF World Championship.
Smart Rabbit Strengths
- 100% free - no hidden subscriptions
- Natural conversational AI
- Daily mental tracking (MCS Dashboard)
- Interactive React programs with videos
- Real-time adaptation
2. Fitbod - The Paid Veteran
Score: 7.5/10
Fitbod remains a reference with its muscle fatigue algorithm. In 2026, it improved its interface but the price remains high ($100/year) and conversational coaching is absent.
3. Hevy Pro - The Social Tracker
Score: 7/10
Hevy added AI suggestions in 2026, but remains primarily a tracker with social features. No complete program generation.
4. Strong Pro - The Minimalist
Score: 6.5/10
Strong focuses on pure logging. New AI features are basic and don't replace a real coach.
5. Juggernaut AI - The Strength Specialist
Score: 7/10
Excellent for powerlifting, but too specific for general bodybuilding. High price for a niche.
