- Instant metabolism boost: Want to increase your body's fat-burning potential? It only takes an hour of exercise to change your body's DNA to increase your metabolism, a new study said. In fact, the effects can be seen in as little as 20 minutes - good to remember the next time you're slogging away on the treadmill.
- One-minute intervals: Here's another reason to love those high-intensity intervals: a study found that just one minute of high-intensity intervals followed by one minute of rest, for a total of 20 minutes, can increase your energy, regulate your blood sugar, and increase your body's oxygen production.

The holiday season can fight against the body's natural desire to relax and hibernate. But instead of putting on another pot of coffee - or worse, a sugary soda or energy drink! - try one of these quick techniques to boost your energy level naturally.
