In this article we will talk about how to choose the right Olympic barbell from CrossFit® or Crosstraining.

The barbells from CrossFit®, Crosstraining, Powerlifting, Wheightlifting, are not all the same and are not all made with the same materials. I differ from many of them. Making the wrong choice of a barbell might bring you a series of really unpleasant chain issues later on then here is a step by step guide to choose the best barbell for your needs.

Let’s start with the terminology and specifications to always keep in mind when buying an Olympic barbell.

What is an Olympic barbell?

An Olympic barbell from CrossFit® has certain characteristics and is used specifically for this sport. An Olympic barbell from CrossFit® or Crosstraining for example has specific standard dimensions that are below:

Men’s Olympic barbell:

  1. Weight 20 kg
  2. Grip diameter 28 mm
  3. Length 220 cm

Women’s Olympic barbell :

  1. Weight 15kg

  3. Length 205 cm

Olympic barbell bar Junior :

  2. Grip diameter 25 mm
  3. Length 150-180 cm

Building materials

The building materials of this type of barbell are high quality steel and chrome for the top coating to protect against sweat corrosion, magnesite, in addition are equipped with roller bearings to speed up all the exercises that need a quick rotation, see Clean&jerk and have a high response to the storage of elastic energy that is obtained with a mixture of dedicated metals.

But why stop there ? We also discover other types of barbells for sports such as weightlifting, powerlifiting and more. Let us see together the difference between the types of barbells.

Difference between Olympic barbell and powerlifting barbell

A powerlifting barbell differs from an Olympic barbell thanks to many features.

A powerlifting barbell is first and foremost more rigid, such rigidity is used to better adapt to heavier loads and logically offer more stability during the lift, different is also the elasticity of the type of barbell. In fact, a characteristic of the Olympic barbells is precisely the elasticity called in jargon “whip” which is nothing more than the ability to store elastic energy.

An Olympic barbell from CrossFit® for example differs from a powerlifting one also thanks to a different knurling. The so-called “grip marks” are closer and are used to control the positions of the hands in official competitions unlike the Olympic barbells where such “grip marks” are nothing more than reference points.

Another difference is the use of bushings in the barbells from powerlifting instead of the roller bearings used in the Olympic ones, since these special barbells do not require rotation speed, on the contrary.

So, to sum up. Most powerlifting barbells have the same weight and size as an Olympic barbell, but are designed with less whip and stronger knurling.
