All great gyms start with the basics...
And A high quality Bar is the most basic and important piece of training equipment in your gym.
All Olympic Bars are designed to fit a plate which has a 2" diameter hole, which is generally called an "Olympic Plate". If you need a thick bar for grip work, a set of fixed barbells, a log bar, or your own personal challenge barbell, you can find them at Atomic Athletic.
Don't let low quality bars hold you back.
