Feedback, progression, goals, and history contribute to personal exercise rankings.
ARC tells you what to aim for so you're not going in blind.
Equipment taken? Swap an exercise for the next best option.
Weights and measurements use the system you're used to.
Large, thumb-friendly actions keeps logging practical on a phone.

Fixed training splits programme volume and exercises based on the split-maker's experience and body. ARC instead generates the right workout for your body on demand - factoring in your personal constraints, goals, history, and preferences. So, if you miss a day, ARC will put you right back on track.
As long as you're honestly filling in the check-in, ARC will know when it's better for you to rest. If your check-in leaves too little worthwhile training, ARC will recommend a rest day. You can still override that recommendation and request the most sympathetic viable session if you're desperate to get a session in.
Each workout, you'll log completed sets, reps, load, and intensity, plus optional feedback for each exercise which really helps ARC adapt to your biomechanics and physiology.
No. We wanted ARC to give you the best output every time, and AI models can't guarantee that. ARC is instead making decisions based on thousands of calculations based on real biomechanics and hypertrophy research data.
No. ARC records your training-relevant readiness and provides exercise-planning guidance. It won't diagnose injuries or replace qualified medical advice.
ARC is being tested with a small group of real users while sections of the app are polished using your feedback. Features and recommendations will continue to improve, and as a thankyou for providing feedback you'll receive lifetime free access.
