Have an incisional hernia, surgery not for 2 months. ok to exercise strenuously until then?

Why not: Yes you can and there is no reason why you can not as long as it does not cause you any discomfort and/or pain.

Probably: You should let pain and discomfort be your guide to activity level. Listen to your body and use common sense. Some exercising may actually make your postop recovery easier. Good luck!

See below: Would advise that it is probably not in your best interest to exercise strenuously before the repair. Would suggest you discuss directly with your surgeon.

Depends. : Depends on how likely it is for your intestine to be squeezed or get trapped. Some hernias are low risk and exercising is fine. Others have a high risk of 'strangulation' and exercise should be avoided. Best to ask your surgeon which type you have. If you have a lot of pain nausea or bloating with activity -- you probably should hold off.
