The 3 Categories of Weight Plates

No matter home or commercial use, it is very important to understand the differences between and purposes of the three categories of weight plates available in the fitness industry.

1-Olympic Weight Plates have a 50mm / 2" diameter center hole, this is the standard size across the fitness industry anyhere. They fit all commercial Olympic bars and all Sterling range gym equipment. Joinfit only carry this type of weight plates.

2-Standard Weight Plates only have a 26mm/ 1" diameter hole and will not fit on an Olympic bar. Though they are made with much more inferior materials and lower tech production process, they were once popular for home gyms. However this has changed because prices of commercial range equipment dropping a lot in the recent decade. Joinfit DO NOT carry any bars or weight plates from this category.

3-Studio Barbell or Weight Plates are specific to group exercise. They have a small 26-30mm center hole, often an essential tool in classes like Les Mills' body pump, in which participants typically do not work with very heavy loads. These weight plates are usually rubber or plastic coated, smaller in size, with grips or handles and colorfully colored. They are much smaller in size and therefore are easy to store, Joinfit carries one very good quality example of such barbell here: https://joinfit.hk/product/bodypump-barbell/
