Just looking for some anecdotal updates...
Yesterday at work (a sports nutrition store) I was chastised by a co-worker for suggesting to a customer that mixing a weak soloution of half a serving of weight gainer in water and sipping it during a workout is an option he might explore. My co-worker offered the "Eating during a workout will divert blood to the stomach and away from the muscles" argument. I countered that we were talking about a watery shake with protein, simple carbs and creatine-not a steak.
But, perhaps my thinking is outdated-I read the articles here on using a half serving of Surge during a workout at least five years ago, the science may have changed. Personally I enjoyed the Surge during training, and I think it was a part of some recommendations set out by Dr. Berardi as well as Coaches Thibs and Waterbury. This was of course before the Biotest BCAAs were available but there you go.
Does anyone still follow this protocol?
