I had a c-section and it's normal, my oldest is 7 (the c-section child) and I still don't have all the fellings back. And my youngest is 4.
Yes, your tummy can get as tight as it was, unless you really gained alot of weight and have loose skin.
Don't go under 1200 cal a day or you will not lose weight, your body will think that it's not getting enough food and go in starvation mode and keep everything! And if you really excersise as much as you do you should eat more! But healthy stuff! The way you execise you should be eating 6 small meals a day!
Visit www.oxygenmag.com and www.calorieking.com They're really great sites for execising and food and motivation. And what I like about it, is that the women in there are in there 30 and 40 and 50 and look awsome!! The other magazines (shape, fitness ect..) their all younger witch I can not compare myself to.
you can overdo it and hit a slump, were your body will just stop, you should not train the same body part 2 days in a row. EX: day 1-legs and shoulder (wall chair stand and shoulder press)
day 2-arms and butt (bicep culrts and squats)
day 3-back and legs(flys and calvs)
day4-shoulder and butt(lat. lifts and lunges)
day 5-arms and legs(triceps and dead lifts)
day-6- well deserved rest
And after a month switch exercies.
But really, get an oxygen magazine, I think that you will love it.
Why not get a babysitter and go to the gym together, that would bring you guys so much closer, and you would be without a child for a couple of hours, even if it's twice a week!
Good luck, take care and talk(write) to you soon to get news :0)
