4. You hate your workout.
No matter how many calories an activity promises to burn, if you don’t enjoy it, you’ll be less likely to do it and won’t reap the benefits. Think of it this way: If you burn 300 calories every time you exercise, but you dread it so much that you skip one session a week, it adds up to 1,200 calories a month. Instead, find a workout you want to do, rather than one you feel like you have to do. When University of Nebraska–Omaha researchers polled women who’d been exercising regularly for longer than a year, they found that one of the top predictors of adherence was choosing enjoyable activities. Study author Jennifer Huberty, PhD, also suggests experimenting with ways to make exercise more appealing. For example, if walking is your workout of choice, try recruiting a friend to join you.
