Exercise - What do you do?
Regarding what you can do, your doctor is the best source. I had laparscopic (NOT open) RNY on March 2. One week ago, he told me I could go back to the gym but we discussed only the stationery bike. He cleared me to go back to the pool (where I am doing stretching and light cardio, i.e., 10 min. and working up past that). I was very surprised he would clear me for this but I am healing fast (i.e. my incisions have been close for some time). So I wouldn't generalize from that.
I plan to give it one more week and then call him re the weights. I've had a couple of complications and am not feeling all that great, so will probably be slower than someone who had the ideal situation.
