Generally a 30mm or 32mm shaft is perfect for bench pressing. It’s a little thicker than some other bars, but for pushing movements you should like that thickness because it doesn’t dig into your hand so much when you start getting to heavy weight.

The best bench press bar path is one where the barbell follows a slightly curved descent and then a “J” curve on the ascent. This involves scooping, or pushing the bar towards your head as you come off the chest and then moving into a vertical bar path once you’re closer to lockout.

Yes, you can bench press with bars of these lengths, but each has its advantages and drawbacks. The 4ft and 5ft bars are generally used for specific exercises or in tight spaces. The 6ft bar is a good middle-ground, offering a balance between compactness and the ability to load a good amount of weight.
