I had a c-section 5 yrs ago. I lost all the weight in the 1st 3 months. (i tried really hard) unfortunately, my mid section was still bigger... goodbye abs.
now 5 years later I have packed on about 20 lbs. For some reason, I find the need to finish whats left on my kids plate =(
When I was slimmer & had abs, I found the ab wheel to be terrific. It was hard to do. hard on knees & back, but they are super cheap & fit anywhere. (just a wheel w/ handles on the end) I got mine at walmart years ago. maybe target or a sporting goods store would have one too. Just take it easy at first.
remember it takes time to get back in shape. It took 9 monts to get out of shape right? stay positive, you basically just gave birth!
Saldly its part of having a baby. Genetics play a huge rule on how fast you slim down as does your diet and how much exercising you are getting.
