I have had 5 pregnancies including twins. My last DC was a 10lb er and I could clearly see him moving about in late pregnancy as my stomach muscles had no tone.
I still look 6 months pregnant and he is 9! I work hard at the gym and do lots of cardio and weights including the crosstrainer rowing machine and crunches (100 a session). The rest of my body has improved but not my stomach.
Anyone improved this through exercise? I am pretty sure I have the diastasis recti thing where the stomach muscles have separated.
