01Your injuries

Tell him about your knee once.

From then on it's just true. Arnold picks different movements, keeps the loading off it, and tells you why the session looks the way it does, without you raising it again.

02Your gear

Dumbbells only? Fine.

Two dumbbells and a bench in a hotel room, or a full rack on a good day. Arnold programs only what you can actually pick up, and rewrites the whole session the moment that changes.

03Your level

One to five, and it moves.

Beginner through Advanced, set once and then earned. As your logged sessions stack up, Arnold suggests moving you up and programs heavier, denser work to match.

04Your joints

Warm-up and cool-down, built in.

Sessions come out as real structure: warm-up, main work, cool-down, in that order, checked before it reaches you. When the session calls for prep, it's already in there.

Hands-free execution

Phone in your pocket.
Coach in your ear.

Arnold calls every exercise, every set and every rest out loud. The clock is timestamp-driven, so it keeps perfect time on the lock screen: screen black, phone away, music ducking for each cue instead of fighting it.

Not shipped yet. The button drives the lock-screen cue sequence. The real recording (Arnold's voice and beeps over a live set) still needs capturing on a device; the player is wired and waiting for the file.
