About Obby: Pump Up Your Muscles! 1 per second

Obby: Pump Up Your Muscles! 1 per second drops you into a prison gym where physical strength is everything. You begin weak and scrawny, but each workout session at the various exercise stations gradually builds your muscle mass and power. Move between push-up bars, sit-up mats and pull-up stations to train different muscle groups, then refuel at the canteen to keep your energy up. As you grow stronger, you'll climb the prison hierarchy and unlock new areas. The steady progression from underdog to powerhouse keeps you motivated, and PokiGame Arcade hosts the full experience so you can train at your own pace. Watch your character transform rep by rep—consistency is the key to earning respect behind bars.
