Growing up it would have been bodybuilders (of course Arnold). Early in my career as a trainer it was my peers (trainers who had been around for many years, with a ton of education) as well as Chek, Wolf and Cook. Today I still look back to all of them for motivation and guidance, but now I also look toward younger trainers for a fresh look at life and to remind me to keep learning.
Petra Kolber. I used to watch her on FitTV 20+ years ago when I first started teaching. I loved her smile and energy and sense of humor along with her easy to follow flowing dance routines. I used to borrow choreography from her way back when and have loved seeing her and learning from her at IDEA conventions since.
