The StairMaster is the epitome of a love/hate relationship. On the plus side, it burns calories like no other and tones your butt (and who doesn’t love a toned butt?). But on the downside, it’ll make your legs feel like they’re going to fall off. Sure, you may hate this extreme sweat-inducing workout at first, but don’t worry, you’ll probably hate it a little more the next day when walking is a near-impossible task. But after you get over that hump, you’ll feel amazing and realize that the stair climber is actually the best cardio machine at the gym! And we guarantee that your mind will wander to these 14 thoughts during your workout . . .
