MuscleCat

Every workout you actually finish makes your cat stronger. That's the whole idea behind MuscleCat — a real strength and hypertrophy training app with a gamified twist that rewards training you actually complete, not just opening the app.

Train for real Build a custom workout plan — Full Body, Upper/Lower, Push/Pull/Legs, or your own split — or start from one of the built-in templates. Set your sets, reps, and rest per exercise, plan your weight progression week by week, and log every set as you train. A rolling rotation keeps your plan on track even if you miss a day — no fixed calendar, no guilt trip.

Watch your cat level up Pick a starting cat companion and name it. Every completed workout earns strength points, and enough of them level your cat up through six evolution stages — from a scrappy beginner to a full "Mega Buster" powerhouse. No passive gains: your cat only grows when you actually train.

Explore ArnoldCity Once your cat is strong enough, new spots on the map unlock — gyms, a pharmacy, a supplement store — each with its own flavor and free consumable boosts for your next workout.

Track real progress See planned vs. actual weight and reps for every exercise, week by week, so you always know whether you're on pace — no separate spreadsheet required.

Genuinely private MuscleCat works entirely offline. Your profile, plans, and workout history are stored only on your device — no account, no sign-in, no ads, no tracking. What you train is nobody's business but yours.
