Why are bearings important? 

Bearings are introduced into barbells to ensure a smooth and/or fast spin when performing Olympic weightlifting movements. This spin reduces the force exerted on an athlete’s wrists during these movements. The BLK BOX Oly Bar has 10 sets of needle bearings, ensuring a smooth spin under heavy loads and reducing the torque experienced by athletes during the movements.  

Why is whip important? 

Barbell whip is phenomenon best recognised where the bar seems to bend during a movement, then snap back into its straight position. It allows the athlete to introduce momentum into their lifts that is caused but the bar, and not by them. A lifter can use the whip of the bar to help propel the weight upward adding incremental gains to their training. Although it removes some stability from the bar, a bar with high whip can handle a lot more weight before bending permanently than a bar with lower whip.
