Everyones criteria will be different with regard to the return to activities after tummy tuck surgery. It's best to discuss this with your plastic surgeon. Based on your type of work and exercise regimen, your surgeon will be able to personalize the activity recommendations with regard to work and exercise.
In general, if a patient has a relatively sedentary job, they can return to work by about 2 weeks postop. If their job involves a lot of lifting, I generally recommend that they recover for about 8 weeks before resuming anything that will put pressure on their core abdominal muscles. This recommendation also applies to core exercises.
Thanks for your question. Best of luck with your surgery!
