True enough. "I was tired" is a total cop-out.
If they're recording and posting video in the first place probably have the ability to edit as well. Tha's the key. Edit out the lame stuff and focus on the good portion.
If they cant look good with that most basic element of muti media production at their disposal then it's probably indicative that their whole workout was weak in the first place.
As for being brave by posting things online? Man, courage has @#$%-all to do with posting things on youtube. All one needs is stupidity. There's plenty of that to go around.
