Working out is a daily routine for Dan, who meets his friend Lonnie at the gym to lift weights. But breaking a sweat takes on a whole new meaning when Dan sees Gene, a professional bodybuilder, in the mirror. Dan knows it's a lost cause: he's forty and nursing a broken heart, nowhere in the same league as gorgeous Gene. Then at the gym the next day, Gene asks Dan if he can work out with him. A bet wins Dan a smoothie and conversation, which surprisingly leads to a date. Now Dan is faced with a dilemma: does he allow Gene to elbow his way into his life, or will he give up on the idea of a new relationship before it even starts?
