This has happened to me several times, and I'll explain what I mean by Weightlifting Plateau, since it's a term I came up with since I can't think of any other way of putting it.

I'll start working out, and slowly increase the amount I'm lifting. Then I get to a point where I hit a certain amount of weight that I cannot do full set of reps no matter how long I keep using the same weight.

Over the years, I would finally get too frustrated and end up quitting the work-outs. Then later start again, build up to a certain amount of weight and get "stuck" again.

In the last year I feel I have put on some decent muscle (decent as in I can see a little definition now, which is good since I was always waaaay to skinny), but it seems like I haven't made any major increases in weight and I feel like I should be capable of lifting more.

Has anyone else experienced this? Getting to a weight that seems impossible to get past and move to a higher weight? Any advice on how to get through it? Thanx for any advice you can give.
