Knurl: Strength Training Coach

Under 18? A new question at sign-up (and once for existing accounts) turns on the coach's conservative mode: no max-effort testing, smaller weight increases, reminders to train with an adult present. You can change it any time in Profile. The starting-weight estimate for a new exercise stays within what you've actually lifted, in your own unit. The "add weight next session" tip knows your gym's heaviest dumbbell or kettlebell once you've told the coach — at the ceiling it suggests reps or a slower lowering instead. A template saved from a gym scan shows its exercises immediately. Terms of Service: added a section on minors and adult supervision.
