    what is this?

    Today was my upper body day and I was doing bicep curls 8/8/10 at 30 lbs. I'm on my third set and try to do my 7th rep. I get the dumbell half way up and it sticks so I put everything into lifting it up and my arm goes down. It's like my arm just gave up on me. What is this/why does it happen? Keep in mind I'm new to weight lifting altogether.

    That sounds like a phenomenon known as failure. Basically, you pushed your muscles to the point where they could not perform another rep.

    You'll get used to it as you lift more, your muscles just quit, you hit the "I'm done" wall.
    Give chalk a chance.
