Old time strongmen would train with homemade equipment. This stuff was made from whatever they could get their hands on, and came in varying grip diameters and shapes. Thick bar, or fat bar training was born. The world’s elite strength coaches have caught on, and professional athletes, bodybuilders, and strongmen have known about fat bar training for years. You will develop not only greater grip strength, but improve your overall strength as well. You’ll also increase stability and improve structural balance in your upper extremities, possibly reducing pain from tendinitis or other repetitive use/imbalance injuries.
