Hi, I am 63 and have upper back bulging disc from an operation where I was rolled improperly on there operating table back in 2017 and its been painful. It might be one of the factors of my brain fog and memory loss. I am brain type 1 and they recommend lifting weights twice a week and walking fast 45 minutes 4 times a week. I am unable to do that. Can u recommend some alternatives even if its just stretching as I’d like to follow the plan as close as possible. Thanks
