You are going to LOVE these workouts! I started my weight loss journey doing the cardio max dvd 6 days a week in the am before work and walking my dog. I changed my eating habits, not drastically, and drank lots of water through out the day and I lost a good amount of weight in just one month. The cardio max dvd let's you choose how long the workout is, it has three different levels. You start with the beginner level, i think they call it week 1 or something like that and you do just the first level for 2 weeks and then after 2 weeks you add level 2 so now you are doing level 1 and 2 for 2 weeks and then after that you add level 3 and are doing all 3 levels for 2 weeks totaling 6 weeks. I started looking forward to seeing Bob, Jillian and Kim every morning. And you only need a small set of dumbells, well actually i think you only really need one to add some difficulty. Mine was only 5 pounds and I used it the entire time. Theres this one part where Bob has you getting on the floor and holding pushup position. When I first started that was KILLER but as the weeks went on it got easier and easier. I used to not be able to do a single pushup on my toes, so I just did the modified on your knees type. And now I can do about 20 at a time. And you don't even have to do just one dvd at a time you can combine the other ones you've bought too depending on how much you wanna work out. I really love the bl dvd's they were a great start for me and I think you will love them too.
Sorry I rambled so much but i'm just so excited for you!
Edited to add: If you'll notice, I was around the same weight as you for starting out so don't let yourself get discouraged when it gets rough. What I love about the bl workouts is the people on the videos aren't extremely skinny like you see in other home workouts. They aren't 'beachbodies' they are overweight people just like us and they are sweating it out! I kept telling myself that if they could do it I could too.
