"I've been running ultra-marathons for many years, and while I have had great results up to now, I was looking to take my performance to the next level. I wanted a strength program that would provide functional, all-body strength, and not compromise my running training. Factor 3 gave me exactly that. My posture and core strength has improved dramatically, and has actually helped prepare me well for an upcoming 100-mile trail race. For athletes who are looking to step up their performance to another level, I highly recommend the Factor 3 program. "
