What's your general rule of thumb on working out on less than five hours of sleep per night? (Or whatever your threshold of sucky-sleep is?)
I usually do better sucking it up and having some productive hours afterward. In fact, I did it the other day. Son woke me up throwing up so I cleaned vomit for an hour and had trouble going back to sleep, so I actually only slept four hours. I still did a butt-kicking workout from 6am to 8am involving running, lifting, and swimming. But, by 11am I was barely functioning. I had to take a nap during lunch and I did feel better.
I actually took the next day off from working out even with an eight hour sleep that night. So, you can do it, but you will pay for it and eventually have to pay it back.
