7 Best Workout Apps of 2025: Tested by Real Athletes
We tested Nike Training Club, Peloton, Fitbod, and more over 8 weeks. Here's which fitness apps actually deliver results and which ones aren't worth your subscription.
Why Most Workout Apps Fail
The average person downloads a fitness app, uses it for 2 weeks, and never opens it again. The problem isn’t motivation — it’s that most apps are designed to impress rather than to work.
We tested 7 apps with a panel of 12 people ranging from complete beginners to competitive athletes. We tracked adherence, progress, and satisfaction over 8 weeks.
1. Fitbod — Best for Strength Training
Fitbod learns from your training history and generates personalized strength workouts based on muscle recovery. It knows when to push and when to let muscle groups rest.
Who it’s for: Anyone doing gym-based strength training Standout feature: AI-generated workouts that adapt to your equipment and recovery Price: $12.99/mo or $79.99/year Rating: 9.2/10
After 8 weeks, our strength training group averaged a 15% improvement in tracked lifts. The app correctly identified when testers were pushing too hard and reduced volume automatically.
2. Nike Training Club — Best Free Option
NTC is genuinely excellent and genuinely free. Over 200 workouts across strength, cardio, yoga, and mobility — all guided by video with professional trainers.
Who it’s for: Anyone who wants structured workouts without paying Standout feature: Quality video instruction, no subscription required Price: Free Rating: 8.8/10
The library is broad enough for years of varied training. The only gap is personalization — it doesn’t adapt to your progress.
3. Peloton App — Best for Cardio & Classes
You don’t need a Peloton bike. The app’s library includes cycling, running, strength, yoga, meditation, and outdoor walking. The production quality is unmatched.
Who it’s for: People who enjoy instructor-led classes and variety Price: $12.99/mo Rating: 8.5/10
4. Strong — Best for Powerlifters & Barbell Athletes
Strong is the best workout logging app for serious barbell training. Clean interface, smart PR tracking, built-in 1RM calculator, and the best log export we’ve seen.
Who it’s for: Powerlifters, Olympic weightlifters, barbell athletes Price: $9.99/mo or $39.99/year Rating: 8.7/10
