Why are bearings important? 

Bearings are introduced into barbells to ensure a smooth and/or fast spin when performing complex weightlifting movements. This spin reduces the force exerted on an athlete’s wrists during these movements. When performing bicep curls or similar exercises, bearings are very important to ensure the force is felt through the athletes’ biceps, and not their wrists.
