When you’re not challenging yourself in your workout routine your body will burn fewer calories. If you are a runner and have run the same route every morning for two months your body will get used to it. Try HIIT workouts instead to get your heart rate higher. This will help you burn more calories, tone different areas of your body, and help the fat come off. Instead of running flat on the treadmill try hill sprints. Anytime you switch up your workout no matter what the switch will be your body will have to burn more calories and build more muscle to adjust to the change, helping your metabolism rise and kick off some of those stubborn pounds.
