Non-Negotiable

Make a deal with yourself that you only have to exercise for 10 minutes. Set a timer, and if you still want to quit when it goes off, you can.

You’ll usually find that you want to keep going, but if there are days that you don’t, that’s fine too.
 Put your workouts in your calendar just like any other important appointment. Make it non-negotiable, and schedule other events around it.
