Another video, which shows a clearly exhausted Larry attack the exercise bike, was also inundated with comments like: "Way to go Larry! Doing great!"

And on a video of Larry a pull-down machine, Larry writes: "Get up get out and do something. I did."

"Much respect! You can do it!" came the comments.
