Donn,
I am a girl and a k poucher but for me, a pouch is a pouch...you didn't tell how old you are, in what physical condition you were/are and what your general healthy is like so those are also factors...
I used to lift, a lot (was a powerlifter pre-pouch but continued lifting afterward, just not as high weights)...as a 'kid' I could lift, push, pull and pretty much do whatever I wanted with my body...but these last 10 years I ended up discovering that my body has limits and that hernias are not my friend...
30 years ago, post pouch creation I thought that I was indestructable but I have since realised that the human body has limits and if you love your pouch then you do not over do it for any reason...I did stairmast 6 weeks post pouch revision...and split, herniated and generally destroyed 6hrs worth of surgery. Waited 8 weeks the next time with the same result. It took a lot of pain and surgery to wrap my brain around the fact that I will never be able to do what I did before and that I shouldn't either.
So, if your doctors says no, then it is no. There are other ways to keep fit, get a hard body and stay healthy without putting your pouch and health in peril.
