Wow! 45 minutes is great!
Here's my story:
I've lost over 65 lbs. in 6 months doing Atkins. I joined Curves January 19th. Yesterday was my weigh and measure day (30 days)...I've lost 11 inches in one month. I really think it's benificial to work out where you can work each part of your body. I liked hearing that I lost in my arms, thighs....I think that if I had continued the diet without exercizing, that I would seriously lack muscle tone. The treadmill is great for your heart and you're burning off some serious calories and fat.....but I would recomend adding weight training.
