Change the way you think. Holly Rilinger is a master trainer for FlyWheel and Nike. And here’s her advice: It’s all about shifting your mindset. If you normally tell yourself “I don’t have enough time to work out,” try this, instead: “It’s not important enough to me to work out.” Rilinger says when you mentally disagree with that comment – and you will – it’ll boost your motivation. And you’ll be more likely to hit the gym.
