Try These Cardio Workouts at the Gym When You're Sick of Your Usual Routine

If you hit the cardio machines at the gym often, things can go stale real fast. But the classic pieces of equipment you'll find in every gym–the treadmill, elliptical, stationary bike, and stair climber–don't have to be boring as long as you make an effort to switch things up. If you're fresh out of ideas, take a look at this compilation of the best cardio workouts for the gym. Whether you're in the mood for a quick and intense workout or a longer, lower-intensity option, you'll find the cardio workout for you.

Total time: 35 minutes

Warm up for five minutes. Do the speed bursts here at the fastest pace you can safely maintain (power walking, running, cycling, using the elliptical or stairclimber) for the given duration. Cool down for four minutes.

Total time: 16 (advanced) to 29 (beginner) minutes

It's easy: Speed up for the number of seconds listed for your level, then go at an easy pace for a minute or two to recover. Repeat eight times for a complete cardio session. (Related: These Full-Body Cardio Workouts Are What Your Exercise Routine Needs)

As a warm-up, spend 3 minutes on a light walk or jog followed by 30 seconds at 50 percent effort, 30 seconds light walk or jog, 30 seconds at 75 percent of maximum effort, and 30 seconds light walk or jog.

Choose your level at left and repeat the circuit eight times to complete your session.

Trainer's tip: If you're using a treadmill, there's a lag of 5 to 10 seconds that it takes the belt to reach your target speed. So the sprint time starts when the belt actually hits your selected MPH, and the recovery starts once the belt returns to walking speed.

Spin away calories with this cardio workout at the gym you can do on a stationary bike from Orest Ludwig, a personal trainer at the Sports Center at Chelsea Piers in New York City.
