Hello Lromano. This is a difficult question to answer in a way to suit everybody, because we are all different in the way the body reacts to exercise. I got my hernia before leaving hospital and not doing anything stenous that I can recall. Since then I hav e gradually and progressively exercised to the point where I more or less do what I did before and it hasn't adversely affected any of my hernias. However, it was a slow and careful process to see what I could do and I always wear a hernia belt ( or two) as a precaution whenever exercising.
There is an old post in 'Premium Content' - 'Hernia and ostomies' - 'Pilates and ostomy with hernia', which has some useful comments with regard to exercise and they nearly all proffer caution - but none of them suggest not going for it.
I hope this is helpful
