You can try fast walking every day for the beginning. Loosing fat will take away your belly and localized exercise than can give you a "6pack" ; ). If you just isolate to exercise your belly - you will not have wanted results.
So, all in all, start slow and start with light aerobic exercise which will benefit your whole body : )) and healing rate.
I was able to go to a treadmill 8 weeks post op . Would put some Vaseline on the anus though, to prevent chafing. After 12 weeks I was able to do all kind of exercise , but I was healed at that point :roll: So, just take it easy.
I would strongly recommend walking though since it will help with circulation and healing in general (now I only wish I can take my own advice LMAO and start exercising again

)
