OSO Kids Mini Barbell



OSO Mini Barbell

We believe that it is very important to have a complete free range of motion when children are learning to use a barbell. The ideal bar for kids would be a light weight bearing bar but they don’t currently exist. We also know that traditional bearings are very expensive. With that in mind we set out to create a bearing bar by machining the bearing surfaces into the bar and sleeves instead adding the cost of buying them. By doing this we have created a free spinning bar at a fraction of the price.

The mini bar is built for technique purposes for smaller athletes (children). To achieve the light weight of 5 lbs. we build them out of aluminum which can bend under excessive impact and/or force such as dropping from overhead. Please be mindful of this when using it during training. Put no more than 50lbs on the bar during workout.

Please note that these bars are anodized, therefore you will notice wear on them as they get used.


OSO Barbell will warranty this product from defects in material, functionality and workmanship for a period of 2 years from the date of purchase. Please contact us at and explain the issue. We will either send out replacement parts or replace your bar
