6 Unexpected Ways to Recharge for the New Year

Try: Exercise, even a little bit

Why it works: We know you know that being active improves energy, and we also understand that the idea of schlepping to a group-class treadmill blitz can make you crave a nap, but here's the thing: It takes a pretty small amount of exercise to start reaping the benefits. Just 20 low-intensity minutes 3 times per week, in fact. Researchers at the University of Georgia, in Athens, put non-regular exercisers on that exact schedule (using stationary bikes) and found that their energy levels improved by 20 percent. Their fatigue levels improved by a whopping 65 percent, even more so than those of another study group that engaged in moderate intensity exercise for the same duration and frequency.
