Muscle Run is a funny obstacle dodging game that challenges you to get strong enough to run through brick walls. On your way to the finish line, not only will you have to dodge metal barriers and boxes, open doors and jump gaps, but also collect energy shakes to get that nice body builder, run through walls shape. You can play this game online and for free on Silvergames.com.
Keep in mind that yellow buttons on the floor will open yellow doors. Boxes will decrease your muscle volume. And metal doors are not to be taken lightly, not even in the infinite world of gaming. Complete all the levels with three stars and have fun playing Muscle Run!
