Yes & No
I had my last personal training session this morning (workout post coming), but I was feeling really flat - tired, weak, low blood-sugar-ish despite having a nice big oatmeal breakfast. It's always so disheartening to try to work out when you feel that way.
The redeeming part of it all was the discovery that I can do an unassisted bodyweight dip! I need to work on getting it just a little bit deeper, but I'm pretty happy about it.
