Stop Doing That 1 Workout You Hate
This is your year, this is your time. You don't have to run to lose weight, you don't have to do indoor cycling to be healthy (or cool). If you truly hate running, then why are you doing it? If the answer is "because I have to," you're dead wrong. The same goes for all other activities. Use the new year to find something else that you do love that will have the same kind of healthy effects on your body and brain.
