Not too long ago, Craig Ballantyne (creator of Turbulence Training) interviewed Tony Horton, and posted a link to the audio here.
I quickly lost count of the celebrities that Tony name-checked (Tom Petty! Pink! Annie Lennox! Billy Idol! Ashton Kutcher! Usher!), but overall, Tony comes across as thoughtful, well-spoken, inspirational, and thoroughly un-douchey. He discusses how he got into personal training, how he transitioned into making home fitness videos, and his fitness and diet regimen. It's good stuff. (Really.)
