It's important to find types of fitness that inspire you, that push you to get stronger, and that you actually want to do consistently. That means you shouldn't just focus on "the best fat burning exercises," Yiannis explained, if you hate them. "Using training as a way to 'burn calories' is a rookie error. Collectively speaking, the training you do most often is going to be the best . . . not the one grueling workout that burned 600 calories, and you know you won't do again." Make fitness and moving throughout your day fun so it's easily a part of your life.
