I said concentration curls feel like an aerobic excersize because I don't feel shit in my bi's, all I feel is my breathing getting heavier from lifting. I NEVER said they WERE aerobic.
I guess I did do around 250, I didn't actually remember or check and figured you knew what I was talking about.
Every lift I do I always get either or a burn or pain. That is how I know when to stop, the pain or burn gets too much to the point where I can no longer bring the weight up. If you think this is the "wrong" way to lift, well I have been lifting this way for a year and have gotten amazing gains, so I could care less if you think it is wrong or right.
My point is I don't feel any pain or burn in my bi's anymore while lifting. Since those two are my only factors in my intensity, I am able to up my intensity alot (I was using dbs that were 20lbs heavier than my previous and felt that I could still go heavier.). I also had no swelling and my viens did not pop out in my bi's like they usually do. I am lifting correctly, I know how to lift. I am not cheating or anything like that.
