A Motivational Mind Game That Works
If you find yourself looking for an excuse to get out of going to the gym, make yourself a deal. Try working out for just 15 minutes -- if you're still hating the workout by this point, you can stop without feeling guilty.
Chances are, though, that once you've put in your 15 minutes, you'll feel reinvigorated and want to continue for another 15 or 30 minutes or longer. It's just a matter of getting started.
