I've got a Kpouch and Not a J pouch so lit is slightly different. I've also had a couple dozen abdominal surgeries.
I know how important your sport is to you and to your feeling of 'returning to normal' or 'going back to where you were before'.
But facts are facts. You are/will be colonless and you have new plumbing.
I will not say that you can only lift this much or that much. I do not know what your body can or cannot do. But that isn't the question. The question is, what will it do to your pouch? Will lifting very heavy weight have a negative effect on your pouch or not? Will they injure you or not?
We are all so individual. Our biology as well as how healthy we are and what the disease took out of us and for how long...what meds we too (cortisone? Cipro?)
I was superwoman. I got my pouch in 79, internet did not exist and I pretty much winged it for years. I moved far away and had 0 advice.
The result is that I overdid it on a daily basis. Maybe that actually helped to keep me healthy or it contributed to all of the complications that I eventually had after the age of 40.
You choose...the only rule is that this is not a sprint but a marathon. Take things slowly, listen to your body. Do not push yourself if there is pain. Do not expect to erase time and go back to where you were prior to all of this. Take all necessary precautions.
Decide what is more important to you...but be careful.
