I started training with Jen about a year ago. I have never participated in a training program that has held my attention this long and that has improved my overall condition! I play on an adult soccer league and race dirt bikes. Swinging around iron has improved my core strength as well as my grip! I have so much more endurance on the soccer field and have drastically improved my grip strength for riding my dirt bike for miles on trail rides without my hands cramping up. There is not one area in my everyday life that has not been improved by training with bells! I am hooked!!!!!
