Thick-bar coaching has been around for many years (because it works). Many old-time powerful men were more powerful than modern sportsmen and the cause of this may be the amazing impact of thick-bar work.
The issue is that, due to the heavy price of thick-handled barbells and other weights, only top level sportsmen have been using them in recent years.
Fat Gripz fix this issue. They provide you the comparative of a whole gym filled with thick-handled barbells and thick-handled weight loads for the price of less than one tub of protein. And they will last a life-time.
