Gym equipment questions

[pecha]

Where I go the Smith machine is 20 pounds. Even if yours is 45 it will feel lighter, because you can use the machine to make sure the bar doesnt fall forward or backward.

how can I tell how much it weighs then? is the weight stamped somewhere on it?

They don't have the weight written on them, but I think there are only two standard sizes: 45lbs and 15 or 20(I forget). The ones in the picture you posted are 45lbs and the most widely used (in my experience).

You can't tell by looking. Just pick it up when it's empty. At the gym where I am, the bar on the smith machine is basically weightless. A standard olympic bar is 7 feet long and 45 lbs. I have been a personal trainer for 2 gyms and have never seen a 45 lb bar on the smith machine.

First of all, excuse my lamer's descriptions.
Does the bar for a bench press weigh 40lbs?

There is a machine on which you can bench press safely by yourself. The one like a big structure with adjustable stops just in case you drop the bar. I have no clue what it's called. Hom much does the bar itself weigh on it?

i know exactly what machine ur talking about. idk how much the bar weighs, maybe its 45, but the way the machine is designed ur not actually pushing up 45lb. it feels more like 20 and i think thats what it is... im not sure tho
