Muskl is an AI-powered workout planner. Tell it your goals, equipment, and experience, and it generates personalized strength-training sessions. Every workout you log feeds back into the AI, so the next session is calibrated to your real performance.

The AI uses your stated goals, your training history (sets, reps, weights, RPE), and patterns it spots over time. After each session it adjusts volume, intensity, and exercise selection so the next workout pushes you forward without overshooting your recovery.

Muskl is available on iOS (iPhone) and Android. Tap one of the store badges on this site to download it. We don't currently offer a desktop or web version of the training app.
