Meet the Mind Behind eJ
Dr. Bob Grisdale
Dr. Bob Grisdale is a chiropractor, exercise physiologist, university educator and former pro athlete based out of Toronto, Ontario. For nearly 30 years, he studied sports, fitness and human kinetics, leading him to countless hours of lab testing and innovation before finally creating eJ: The world’s first closed loop tensile resistance device.
