I've been working out pretty early recently. Sometimes as early as 3 or 4 in the morning. I actually enjoy it and it's cool since there's no one else there. 

The other day I was doing deadlifts, then I thought it would be interesting to actually see the contraction in the muscles, e.g. the core, a bit better so I decided to take off my shirt since no one was around anyway. I did my warm up sets and then 5 heavy sets. When I was done I noticed that behind me on the exercise bikes there was actually a young woman who must have entered shortly after me without me noticing.

That made me feel a bit embarrassed and made me think she must have thought of me as pretty vain.
