Bench/Squat Chains

how long should the support chains be when using 5’ length chain with squat and bench?

the ones hanging from the bar in the pic

I like to set them up to be long enough that there are still a few links in the air at the bottom of my bench press. This prevents the addition of chain weight from being jerky and sudden.

Same thing with squat.

everybody will be different. Obviously if someone is 5’nothing will need a shorter chain then someone who is 6’+

Also depends on how much weight you want at the top/bottom, how gradual the weight will increase, etc.
