Yes, disregard it. You can lift weights for a long time without going catabolic, if glycogen is a concern, sip on some carb-drink, like fruit juice, or even some protein shake.</div>
It's not my only concern. Define "long time". What about fatigue, should I disregard that too?</div>
no, fatigue is a problem. If you find yourself losing steam after a hour, then stop. An hour is my limit also, if I am lifting very heavy, then even sooner (40 minutes)I feel CNS fatigue kick in.</div>
I think I was confusing lack of energy and fatigue. I'll consider what you wrote then.
