I'm Ginger, from www.diabeteens.com. Type 1 diabetic for ten years.
Im going to be competing in powerlifting on May 2nd: deadlifting around 300 pounds, benching around 190 and squating about 245!
Here's some vids of the progress: http://gingervieira.blogspot.com/
Either way, a year and a half ago I was just a normal strength female, only because of consistency and adhering to good nutrition, managing my blood sugars and working hard did I manage to get up to a competitive level...but diabetes was never a reason that would keep me from succeeding. I had to work just as hard as any non-diabetic!
You can do whatever you set your mind to! But you've gotta be willing to work hard!
