Just as a tip for muscle gain. Idk what sex you are but muscle burns fat so even girls need to gain muscle. Sorry tangent, stretch!!!! Before and after every workout. Helps tear the muscle more then you already did (helps muscle growth).
Also I don't want to be mean but it won't be 30 days to get you "in shape". Ppl you see on the ads are the 1% who try it. Most of these DVDs and what not aren't a get riped or toned quick tool. You should see them as a helpful step on you way to a better body. USE what she teaches to further yourself beyond the 30 days. THAT is where ppl get fit and stay fit.
Sorry just trying to help out. Also you don't have to go on a HUGE diet to get fit. You can eat normal and still get there. It's just WHAT foods you eat. For instance, you go out and you want chicken. Choices are, baked, grilled and breaded. The Chicken is good for you, how it is cooked is not. Always go with the healther option.
And just 1 more thing. Know when to eat and how many meals to eat. Eating too late is bad for digestion of food and burning it off. Also 4-6 small meals a day are better than 3 bigger ones.
