I ran into a blogger that had many questions about fitness. All her questions led to a great blog post, so I wrote one up for her readers. Please visit I Complete Me Blog to check it out.
Something I would like to add for those that have stomachs that really aren’t going to be flat. Unfortunately, there is only so much that the skin can take. I personally live with the fact that I did not have any information about food or exercise when I was pregnant and I gained over 70 pounds with each kids. I can not put my skin back to pre-pregnancy by diet and exercise. I can tone up, lose the fat, and be healthy. But the skin was severely damaged with stretch marks and will not go back to flat.
I do work hard at being ok with this. I am human however and there are times it does bother me a lot. I know that I am healthy and I look darn good in my jeans.

I was about to asked my friends about that but luckily i had read about your post. It’s really hard to lose weight after giving birth. Me and my sister-in-law were getting annoyed of going to gym everyday but it seems nothing is different from the day we gave birth.We had our diet but nothing had happen.

How long have you and your sister-in-law given it? I know women that have set unrealistic goals. It also depends on how much weight you gained as to how long it could take you to get back to pre-pregnancy.
