OK so I gave birth 14 months ago and i still have a soft belly. I breastfed up until today so i lost a lot of weight just doing that and i think i had time to work out maybe about 10 times ( i work full time). My child is finally sleeping in his crib and i will finally be able to work out at night after putting him to bed. I was wondering what i can do to help tone my belly. I am not bigi weigh 100 pounds so i don't want to loose anymore weight i just want to tone up my loose belly skin how do i do that just plain old crunches?
