At Fitness Destination we carry a large selection of weight bars. A standard weight bar is usually great for a beginner or someone on a budget. These bars are typically less expensive than the Olympic weight bars. A standard weight bar fit weight plates with a 1” diameter inner hole. Where as the Olympic weight bar fits Olympic plates with roughly a 2” diameter inner hole. You will need an Olympic bar if you are using an Olympic width weight bench or lifting using a power rack. Olympic weight bars have become the choice of the more serious weight lifter. Machine bars are accessory items for cable and pulley machines such as home gyms or lat machines.  By using different bars you can target different muscle groups this allows you to get more out of your current machine.
