Q:I often see women at my gym taking two spin or step classes back to back. Is this a good idea for losing weight?
A:"No, it's a shortcut to burnout," says Keli Roberts, group fitness manager at Equinox Fitness Club in Pasadena, Calif., and spokesperson for the American Council on Exercise. Doubling up can also increase the risk of overuse injuries, says Roberts.
A better way to extend the duration of your cardio workout is to choose another activity after class, such as walking. For example, walking on the treadmill or using the elliptical trainer, Roberts suggests. Not only will you work different muscle groups, but you can also go at your own pace and control the length of your workout.
However, don't assume that you'll improve your fitness by simply exercising longer. According to Roberts, people who take back-to-back classes often train at a lower intensity than those who give it their all during a single class. “If you put in the effort in a spin class,” says Roberts, “one session is enough.”
