Who's your favorite fitness guru?

Mine would definitely be Jillian Michaels. I actually feel like I get a workout with her dvds.

I've never done his videos, but I have to say Richard Simmons, though crazy, is pretty damn entertaining when you catch him on various things. Ha ha.

Most annoying: Denise Austin. Ha Ha. I like her workouts, but my god!

I haven't tried anything by Jillian Michaels, but 30 day shred is on my to do list.

My favorite video instructor is Rodney Yee, but I'm not sure if he's considered a "fitness guru."

For a classic fitness thing, so far my fave is Billy Blanks.

I've done many, many workout videos and I have to say Jillian hands down. The lady is a female "Hitler!" 
One of my favorite quote of hers is, "....keep going! You might faint, but you're not going to die!" And the other... "This isn't your moms workout!"
She used to be fat but do you see how tone and thin she is now?

I like Gilad.  I do both his newer shows and some of the old ones where he uses hand wieghts.

Billy, Billy, Billy!    Anyone who can get me to laugh aloud while I'm killing myself working out for him is tops in my book.

But I'm also fond of Tiffany & Max Chen's kick-boxing video.  I like seeing two versions of nearly every movement being performed right next to each other and being able to take my pick.

Yup Billy most def, indeed he makes me laugh!
I like it how he comes close to the camera and cheers you on, also I just plain love his vids, they are easy to follow but kick your butt (I am doing his get ripped advanced work outs at the mo)
Most hated: that evil pixie from slim in six, that little laugh she does when she tells you to do another 8 reps, used to freak me out, yikes!!!!

Alwyn Cosgrove. 

Gilad Janklowicz!

Billy Blanks

Jillian Michaels .. all the way..

"I want you to feel like you are going to die" Not for the faint of heart. But she gets results. (for me, and the biggest loser contestants)

Chris Carmichaels and, well, our very own Melkor. 

Ya, Melkor's info and advice has been the most helpful. It always seems to lead me to the weight room, haha 

aww, thanks guys ;)

 ( I have a couple picks beyond Cosgrove. Lyle MacDonald who out-nerds me handily, and Mark Rippetoe ;)

Tony Horton. I do his P90X DVDs (Just finished the third round).

I'll be starting my fourth round in a week. I'm resting this week, having just run the Big Sur marathon.

If we are talking about old school fitness gurus, though, I would have to say Jack LaLanne. He's in his 90's and still active.

I love Billy. Even though I've alost memorised the work out videos, I still curse at him everytime he asks for one more set.  I used to visualise kicking and punching my ex's while doing the work outs... that was fun! :D

Well, I have several favorites: 

Melkor (of course!), Tony Horton (P90x) and Jillian Michaels ('cause she's a tiny bada$$).  I do like Billy Blanks (Taebo) quite a lot, he's very motivational.

I love Mistress Krista from stumptuous.com.

Tony Gentilcore.

Another vote for Mistress Krista....and Melkor of course!!!
