Muscle Rush - Smash Running

Muscle Rush - Smash Running is a 3D running game where you race across a long bridge and bulk up as you go. You play as an athlete who loves building huge muscles. The game is split into sixteen levels, and in each one you need to reach the finish line in one piece. On the way you run into obstacles like crates, blocks, and boxes. While you are running, you grab energy proteins that increase your mass. The more mass you have, the stronger you get and the more obstacles you can smash through. Avoid the big hazards, break the smaller barriers on each level, and keep your training going from start to finish.
