I would, except for three things;
1) I don't have a 'HD-Video Camera'
2) I'm not yet an expert on all of the exercises.. (soon hopefully!)
3) My gf might not be the happiest with me doing it.
I'm ok with the 3rd part. What she doesn't know won't hurt her.
(It's not like I'm webcam modelling or would doing this for pleasure... plus it's for a bunch of guys not a bunch of girls, so I wouldn't feel guilty)
