The new JRx Grip Trainers are the perfect pain-free performance training tool for getting the most out of the Foundations, Functional Hypertrophy Training and Functional Power Training programs. With a specific size, shape and texture developed specifically for Dr. John Rusin, the JRx Grip Trainers provide a hugely novel  (and cost effective) stimulus for pain-free training that can fit into any gym bag. With the ability to quickly and easily attach to barbells, dumbbells or around bands, the JRx Grip Trainers will add diversity to setups and stimuli of common exercises like bench press, dumbbells rows and loaded carries without the need for specialty equipment like fat bars and thick handled dumbbells, kettlebells, cables and machines. And more importantly, training with a thicker grip on bars, dumbbells and bands reduce chronic stress on the wrists, elbows and shoulders with common upper body exercises like barbell bench press, dumbbell pressing and rowing, while adding challenges to carry variations and direct shoulder and arm work. When used with bands for those who do not have access to cables or machines, the JRx Grip Trainers provide a more comfortable handle to grip onto, reducing pinching and irritation of the hands when using bands only. Simply put, the JRx Grip Trainers will revolutionize the feel and function of common exercises and be a game changer for your pain-free performance training.
