A: No—and you might be surprised at how many calories you can burn by working consistently at a lower level of intensity, where you’re not sweating profusely.

The fact is, you’re burning calories all the time, even when you’re asleep. Those calories come from a combination of fat and carbs. The fat-to-carb ratio changes according to what your body needs, but the difference between a “fat-burning zone” and an “instant-energy carb zone” is less than you might think.

Here’s the deal: if you want to release weight, it’s not about where those calories come from, but how many you burn overall. So, the more active you are during your day, whether it’s a super-sweaty spin class, a challenging yoga session, or a climb up your office stairs, you’re still burning calories. Check out these numbers:

*Average calories burned for an average hour Pilates or Tai Chi class: 200-250 cal

*Average calories for an average hour of jogging (not sprinting) 400-500

If we do some simple math, we realize that there’s no difference, in calories at least, between 5 days of a medium intensity exercise, such as Pilates, Yoga, Tai Chi, or weight training, and 3 days of jogging. Now, jogging for an hour is more than most of us want or need to do, so create an ideal mix for yourself between lower and higher intensity exercise.

The key to really burning calories and releasing weight? Consistent exercise and good food choices.
