Black Iron Strength™ is proud to offer the first Olympic rotating thick bar in the world! It took hundreds of hours in research and development, but we finally cracked the code. Our hard work paid off, though, with our reward being a US utility patent for the concept of an Olympic rotating thick bar (US patent # 6770016). Beware of imitations; no competitor can offer this tool as it is protected by law! The benefits of a rotating handle on Olympic bars have been recognized for a century, but it took until now to witness the birth of the Olympic thick bar with a rotating handle. Now athletes can enjoy the many benefits of thick bar training while reducing stress on the tendons of the wrist and hand that are a risk of a non-rotating design. Thick bars provide training benefits such as a safer, more natural grip for athletes with large hands, thus eliminating what we’ve coined the Grip Gap™ in using bars with smaller diameters. They also provide for superior, individualized sport-specific grip strengthening.
