I know I'm very late on bringing this up, but I love Hulu.com. If they showed the pay-per-view fights or events, I would love this more than I love my beloved Fios (oh plug plug plug, V-zon where's my $$ lol). I can find even work outs on here after they have left the onDemand section.
So, honestly I have an excuse to still come online (well besides coming to my blog lol).
Also if you just want to go ahead and really start to working out, you can go to www.self.com
