It can be annoying and everyone kinda varies but for me: full body 3x per week. I found that walking to gym, then stretching before workout, doing the deed, warm down stretch then walk back home tends to provide consistent results.
I just started both long and short acting insulin because I wanted to come off meds to ease strain on organs (thinking about the long term effects.)
Hypos happen for me if I bike to gym instead of walk. I treat with some raisins or dried fruit and that seems do work then it doesn't come back down after that. Stays within range.
