Signing up for an exercise class is a great way to add variety to your weekly cardio routine. And let's face it — misery loves company, right? Sweating through all that cardio with companions can be a great motivator.
Just be sure that if it's a cardiovascular class, it involves a minimum of 45 minutes of activity and keeps your heart rate up. Go to your local gym or fitness center and see whether you can get in on one of these bad boys:
Spinning: Climb on the bike and pedal to motivational music and instruction. Spinning doesn't require a whole lot of coordination, and you can keep your own pace; in any case, it's a real calorie-burner.
Step: Start marching up and down to the beat of your step aerobics instructor. The stepping motion offers an extra boost to this cardio workout by adding another level of intensity.
Boot camp: This high-intensity workout will kick your butt — in a good way. It's a combination of cardio and strength training, and it works the whole body.
