S&W357,
I'm not much help on diabetes, but have a couple pointers on
going to the gym. I've lifted free weights on and off since my teens.
After one of my innumerable lazy times, I saw some
doctor claim that weights would lower chloresterol. At the time,
I had just been tested for that,=223.
A month later, had another test for insurance purposes=173.
Also, pushing yourself to find out how heavy to lift is
a sure way to get laid-up and lose whatever benefit you had
achieved. The really important part of weights is form and range
of motion.
Sounds like you're doing everything right, now, so you have time
to experiment.
I wish you the best with your condition.
