Build more muscle.


It’s true what they say about muscle burning more calories than fat: Muscle is about three times more metabolically active than fat tissue, so by increasing lean muscle, you’ll burn more calories 24/7 (even when you’re sitting still!). Strength-training exercises, like lifting weights or doing crunches, lunges, squats, or planks will build up your muscle mass, so aim to do about 15 minutes of strength-training two to three times a week, in addition to plenty of cardio.
