I think in my head all the time. Things like "Oh God I thought the leg presses were over", or "Yeah right, I can't do another pushup!"
When she says "Whata Pump!" in HSC I always repeat her and say "Whata Pump!" really loud. My dh and kids think I am nuts!
I do mumble and mutter throughout most workouts, things like "No, Ohh, and Come on!"
