Kathy Kaehler

Nationally recognized fitness expert and celebrity trainer Kathy Kaehler provides you with first-rate health tips, exercise programs, and nutritional facts. For 13 years, Kathy Kaehler was a fitness correspondent on the Today show while training celebrity clients such as Julia Roberts, Michelle Pfeiffer, Cindy Crawford, Jennifer Aniston, Denise Richards, Claudia Schiffer and Kim Kardashian. Kathy’s Koko Smartraining programs are based on Kathy’s books, “Fit and Sexy for Life” and “Mom Energy”.

“I designed these programs to address the trouble spots we all wrestle with, like flabby arms, wide buttocks and love handles where slender waists once were. Together we’ll tighten your midsection and zero in on your target muscles for fast results, just like I have with my celebrity clients.” – Kathy Kaehler

Rob Parr

I believe in packing the most into every workout – building a strong foundation and working hard to build a better body.” – Rob Parr
