Kudos to you for getting in a bike ride, that is huge! You know I put on so much weight with my pregnancy and I was feeling overwhelmed. I did do WW for a while and took off 19 pounds, but I needed more. My husband showed me this book called "The Body Sculpting Bible for Women" it is awesome. You can just check it out at Barnes and Nobles or even online if you like. You do 10 min cardio per day along with a couple reps of sit ups. You do weight training three times a week. It gives you a nutrition guide, but you are already on WW so you are good there. Anyway, there is a page by page explanation of how to do the exercises and a DVD to show you proper form should you need some help. Girl, I love it! I have now come down from an 18 to a 14 and I feel so much better. You start with a break in routine for 6 weeks, then do that routine a bit more intensely for 4 weeks, and then there are harder routines after that. It is designed so that all you need to start are a pair of light weights 5-10lbs. So you might want to take a look at it. It takes about 45min per day, but I just love the way I feel. I don't know about the supplement you were thinking of, sorry. But I toy with the idea from time to time of trying some kind of supplement, but always end up doing it the old fashioned way. Best wishes!!
