Most people see aerobics as being an old-fashioned type of workout (can't you see those old Jane Fonda routines?), but the truth is that it's still highly popular--particularly the step version of aerobics. Step aerobics combines a cardio workout with a lower body (legs, glutes, and calves) workout. It may look a bit goofy, but wait until you've done a full hour of the movement. You'll find that it's an EPIC workout--both cardio and leg training!

The average platform is 5 to 8 inches off the ground, but if you step up to a platform 12 to 18 inches tall, you'll soon be feeling the ache in your glutes and legs. While regular aerobics only burns between 300 and 600 calories, step aerobics can burn between 500 and 800 calories. That's far more calories than you'd burn by jogging or running, and with far less impact on your joints.
