I'm 60 and been a weightlifting coach, personal trainer, as well as a strength and conditioning coach for 35 years. (Former competitive lifter too.) At my age, I still like to experiment with things like supplements and equipment on myself. I must admit that I thought all ab stimulators were gimmicks. I purchased this and have been using it for 6 months. To my pleasant surprise, it has amazingly helped with chiseling up my core even more.
