Yes. Normal Olympic barbells are 45 pounds. EZ-Curl bars are around 20. It's for your own purposes, so you don't have to, but when you start talking weights you should know that most people include the weight of the bar. In some cases, such as, Leg Press or various other machines, just record the weight you add. Be careful when going to other gyms, their platform/sled may weigh a lot more than yours.
