Jane Riley


M.S., B.A. Internationally Certified Personal Trainer, Certified Nutritional SpecialistI have one mantra when thinking about my fitness career, and that it is that; “everyone who has ever read my words, heard my words or met me and followed my advice is better off than they were before.” This code of ethics has served me well over the past decades of my fitness career. I love learning new exercise techniques and expanding my personal repertoire of modalities so that I may better serve those people who become my clients, my students, my readers and my friends. Over the years, my education, and experience has allowed me to successfully train everyone from children with weight issues to the elderly infirm, to world class athletes to those who need rehabilitation. I look forward to meeting you at KAC and assisting you with your exercise program and your nutritional program as well.
