A plan that trains around the injury, not through it
Flag a sore knee and Arc stops loading it. Report an injury and the plan changes the same day. And every week, injury-prevention work is built in — guaranteed, not optional.
Swaps that make sense to a coach
Injury restrictions swap exercises the way a strength coach would: a hip thrust instead of a hinge for a sore back, a single-leg squat instead of a heavy bilateral squat for a cranky knee.
Restrictions show up on the coach’s dashboard, so nobody has to remember who is carrying what.
- Body-map soreness in every morning check-in
- Injury restrictions that change exercise selection
- Coach-set medical review that shifts a plan to recovery
- Player health page with “I feel ready”
