Hey Phil,   In addition to Andrew's response: yeah, there's no reason why diabetes would keep us from putting on muscle. I've gained muscle more easily over the pasy year and a half than many people, diabetes or not, because I train really hard with Andrew, and have made good nutrition a serious focus of my life.   With the diabetes, it's definitely true that if your blood sugars are out of control, you're going to struggle simply in terms of maintaining quality energy, let alone building muscle. That's why I'd written this article a while ago: Other reaons to aim for good blood sugars.   Just like anything, hard work pays off! Consistency and keeping your priorities straight.   If the basics of weightlifting are still foreign to you, like if I said, "Try your deadlifts sumo-stance instead of conventional," and you didn't know what I meant, then it may be worth it to work with a trainer at your gym or contact someone like Andrew to help you design a good program. Because the other HUGE reason I've made so much progress, was that I didn't waste a couple years doing things partially correct or majorly incorrectly on my own!   -Ginger
