Should I work out today if I did not sleep well last night?

I was on a call this morning with a former professional Ironman triathlete. This guy is the real deal. He is not lazy.  He is not unmotivated. He is not unathletic. He is a top tier kind of athletic guy, and he is very, very aware of his body. He is also very adept at the process of damaging tissue we call "training" and the need for healing those tissues to make his body stronger. What he also understands is that the process of healing a ligament sprain (or "injury") is the same thing.  During our call this morning, he pointed out that he barely slept last night. Since his plan was to ride on the trainer today, we were talking about the risk to the sesamoids.  He used a term I had not heard before, calling it "multifaceted negatives." Should I work out today if I did not sleep well last night?  Well, that is a good question and that is what we're talking about today on the Doc On The Run Podcast.
