Whether it’s a lifelong friend or an office buddy, gym partners give you a real boost. “Partners not only help with the motivational aspect, but they can help in getting you better results, too,” says Gray. “They push you a little harder than you’d normally push yourself and make sure you actually go to the gym even when you feel like going home.”
And to make sure you both keep each other motivated—make a game out of it: First guy to flake on the gym buys the other a beer (a light one, of course) at happy hour. Make sure to hold each other to it!
