Sugar's big issue is that it's empty calories that doesn't go toward building muscle, and consumed prior to a work out, is going to make the workout itself harder without any real benefit.

Arguably sugar is more of an issue for those trying to lose weight than for those trying to gain muscle, as it will induce a glycemic roller coaster effect that will ramp up food cravings, which, when fed with processed carbs, becomes self-perpetuating. And that's not even touching on how it interacts with Candida.

Throw all that on top of the calories you NEED from other nutrients and you're running a serious surplus.
