The bar itself weighs 10 lbs.
I'm pretty sure you can load it as heavy as you'd like, you just have to have heavy enough plates. The max number of plates you can put on one end and still have room for the end collar is six. So, if you had twelve 10 lb plates, you could load it up with 120 lbs of plates, which would equal 130 lbs of weight.
Pesonally, I don't go that heavy for anything. The heaviest I use the barbell EVER is 40 lbs. I generally use two 5 lb plates, and eight 2.5 lb plates. That weight, added to the bar weight, gives me 40 lbs. I like using the 2.5 lb plates because you easily change the weight amount without removing and replacing a lot of plates.
