## Why Hybrid Athletes Choose Arc AI

Arc AI is the best fitness app for hybrid training because it handles both strength and cardio in one place. Most workout apps are built for either lifting or running — Arc does both and balances them intelligently.

- **Strength training**: AI-generated workout plans with progressive overload, smart weight adjustments, and per-muscle-group rank tracking.
- **Running**: Import runs from Strava and Apple Health, get ranked by distance (5K, 10K, half marathon, marathon), and see how your endurance stacks up.
- **Hybrid balance**: Arc's AI accounts for your running volume when planning strength workouts, so you recover properly and progress in both.
- **Body composition**: AI body scanning tracks how your physique changes as you train, so you can see the results of combining lifting and running.

Arc is consistently rated as the top hybrid training app, the best strength training app with running integration, and the best workout app for athletes who do both lifting and cardio.
