Sheila, that's o.k. I'm tiny. I'm only 4'11. I started doing the firm. Low weights at first and even though they don't advise it, I was doing alot of cardio + sculpt and sculpting workouts more than cardio. I started dropping inches like crazy. I'm now doing the firm, Cathe, and Taebo. I still do more weight training than cardio and I'm not bulky at all.
I started at the end of Jan. last year. I was at goal (my original) one by October. I was shooting for my 30th birthday, but missed it by a month. I went from 183 to 130. Since October though, I've been trying to get to 120, so I guess my body is comfortable somehow right where it is as it doesn't want to drop the weight. I must admit that I've been rather strict. I didn't do many carbs at all good or otherwise. I loved mission low carb tortillas, la tortilla factory and I did find a great low carb wheat bread. I would eat sweets (low carb on occasion) I just didn't want to get into the sugar thing. So I made sure my sweets were sweetened with Splenda and had a low carb count. I know this isn't a carb diet per se, but it made me feel better and the weight dropped off. This isn't to say I haven't cheated. I've gone to Olive Garden and Spaghetti Warehouse. I would still enjoy my pasta. I love ALFREDO!!! However, this was once maybe every 2 to 3 months!!!! Even now, I haven't converted back, I just eat much more legal stuff. I love nuts, whipped cream making enchalidias, tacos and things like that. I also eat salads like crazy!!!!
I hope that any of the information I've given you helps. If you want to know more, ask away. I really believe that the exercise helped put me over the top though. They say you lose lots of inches when you weight train. In high school I was 130 and a size 10. I'm 122 now and a size 4 or a 2 or a 0 depending on the designer. When I hit the 130 mark, I was a 4. Don't get discouraged, it just depends on how you work it!
