Mr Muscle Guy is a cartoon gym game where you build a bodybuilder from scratch and train him into the most muscular guy on the beach. It comes from the makers of Iron Muscle.
Use the mouse or touch to play. Start by choosing skin tone, eye shape, hairstyle, and hair color. Then head to the gym and work through weightlifting and fitness exercises across nine training programs, each aimed at building different muscle groups.
Time to hit the gym. Mr Muscle Guy is free to play right in your browser on Games321, no download needed.
