"Hop on your favorite cardio machine, then increase the level of resistance by 1-2 levels every two minutes until you can no longer handle the resistance," says Sweets. "Then, work your way back down the pyramid. You will burn more effectively by changing up the intensity." You can apply this to any machine of your choice: bike, treadmill, and even the elliptical to keep you motivated, and make mini goals by upping the intensity as your body adapts.
