Find something that you really love and you'll naturally stick with it. I bought a treadmill, and discovered I hated walking on it. Very mind numbing. I tried walking outside, and it's okay, but in Michigan the weather is unpredictable and 3 young kids doesn't make the timeing very flexible. I started using "walk away the pounds" and just didn't much like Leslie. Then Tae Bo, not for me. So on to The Firm. It was okay, but the instructors were slightly annoying. I did discover with The Transfirmer that I liked Step Aerobics. So, Eureka! Something I finally liked. I then found Cathe and have been working out with her 6 days a week ever since. Exersize is it's own reward. It keeps me energized and happier. I feel accomplished and less guilty about eating something yummy. Good Luck on your journey.
