They say it takes 30 days to make a habit. Give yourself the gift of just 30 days of commitment - so much easier then the rest of your life - and take it 30 days at a time. Pick a goal you can easily exceed - not to far reaching (like I will exercise 2-3x a week) and then for your next 30 days push a little further. You will feel good about meeting your goals and will be on your way to making exercise a habit. Good luck!! You can do it!

another thought - you might want to try some fun tapes at home on days you can't get to the gym.
