The heart was once considered to be a furnace in which the fire of life resides. This fire kept the blood boiling. The heart, as an organ, as a deliverer of the nutrients of life, and as a keeper and destroyer of love, rules both mind and body. Without the heart comes death.

Area of Expertise: Magazine feature writing
Jenny is an Exercise Physiologist, and the founder, author and web developer of truPhys.com. She loves all things cycling, is an avid mountain biker and enjoys the occasional employment of practical jokes.
She also contributes regularly to Singletracks.com, focusing her writing around mountain bike training. She covers events and races with a physiology twist, such as Red Bull Rampage and the 24 Hours in the Old Pueblo.
She’s has been a certified Personal Trainer (CPT) since 2014 and is currently working toward earning a USA Cycling Coach certification. She has coached and consulted with an array of athletes, from amateur to professional, including three-year North American Enduro Tour champion, Kyle Warner of Marin Bikes.
Physiology is a network of networks. Her research interests include: fuel metabolism and bioenergetics, lactate metabolism, the effects of altitude, cold and heat on fuel metabolism, the effects of exercise on vascular remodeling and cardiovascular diseases, and the use of positive psychology techniques in sport.
Jenny enlisted into the US Army Reserves in 2006 as an Engineer. Upon graduation from the University of Cincinnati in 2007, she commissioned into the US Army and ultimately, had a blast (literally!) While stationed in Penn Yan/Fort Drum, NY, as a part of the 770th Engineer Company, she was named the 2010 Army Engineer Association/US Army Corps of Engineers Platoon Leader of the Year for the US Army Reserve. She was also the first female to graduate as an Explosive Ordnance Clearance Agent for the Corps of Engineers. A short time later, she successfully transitioned to work as an Explosive Ordnance Disposal (EOD) technician and a Master Resilience Trainer.
Graduate Education and Teaching Experience
Jenny earned a master’s in Kinesiology (Exercise Physiology) from California State University, Chico. Because she loves nerding out on the inner workings of human metabolism, she also completed a substantive, 3-year course load in chemistry. Her master’s thesis focused on deciphering the differences in how men and women use fat during the postexercise recovery period.
One of her loves? Teaching. Alongside her graduate coursework, Jenny instructed 2 years of Exercise Physiology laboratory at CSU Chico and personally tutored more than 150 students in various subjects, including human physiology, exercise testing and prescription, chemistry and exercise metabolism.
Upon graduating with distinction, she was honored with several awards, to include the 2015 Outstanding Kinesiology Thesis, and an Academic Excellence Award, both presented by the Department of Graduate Studies.
Jenny now resides in Phoenix, AZ, with her husband, David Herbold (an excellent web developer at ASU) and their two cats, Jens and Juneau. She has taken additional graduate coursework as a part of the Physical Activity, Nutrition and Wellness program at Arizona State University, along with an abundance of self study. She currently works part-time conducting dysrhythmia diagnostics at Abrazo Arizona Heart Hospital.
Sports (ok… cycling):
Jenny has always been involved in sports, from competitive swimming in high school to 8 years in the military (where her Soldier’s would tell you she definitely kicked some ass). Her interest in cycling began when she moved to Chico in 2012. While recovering from a running-induced foot injury, she was conned into purchasing her first bike, a Trek Fuel EX8, by two good friends she now regards as brothers (thanks, Tom and Colin!) Mountain and road cycling are now fully integrated into her lifestyle – there isn’t a day that goes by where she isn’t riding, or at least writing about it.
