I've been looking for a bicep exercise that I really liked, and I found someone doing this at my gym:
Using the machine preacher curl, but using only one arm, the man lifted a weight that was much heavier than one arm could handle, but he used his free arm to yank the bar upwards, and once at the top, he pretty much let all the weight go into his working arm, and slowly let the bar down.
I did this only 4-5(!) times, and I felt a burn that I have never felt before doing regular bicep curls.
Do the positive and negative portions of a curl do different things? Is there a problem if you skip the positive (upwards, I'm assuming) portion entirely?

ahhh...negatives, very good question.
actually the technical term is eccentric training (as opposed to concentric/isometric/ecconcentric) and it refers to a type of training where only the eccentric or negative portion of the movement is performed. loads can be anywhere from 70% to 140% of your 1RM in that particular lift!
yes it will do something completely different than your concentric. on the eccentric portion your motor units (indvidual muscle fibers) are getting 1.3 times the amount of load in them, this causes a tremendous amount of breakdown in the muscle. this will in turn cause your body to induce more muscle growth, increase the amount of maximum strength, it will improve your ability to decelerate (slow down) your limbs or any objects, etc.
eccentric training should last no longer than 6 or 7 weeks and should not be used extensively by athletes looking for relative strength. this means the most amount of strength with the least amount of body weight ie: elite powerlifters, figure skaters, boxers, etc. the reps should be kept to 4 to 6 and the sets should be between 2 and 3.
you will need EXPERIENCED spotters for this type of training. along with some more knowledge on how to go about actually training this way.

I agree with the last part nellyboy. While negative training is a great way to shock your system, I would not suggest it to a beginner and only then to those with more exerpience ans as a shock method...not to be done all the time. Hope that made sense....oh yeah Nelly I also agreed with your whole post lOL

LIFT HEAVY! BECOME STRONG, LIKE BULL!

Quoting from nellyboy:

That sounds too good to be true in terms of putting on mass. Are you telling me that the two main drawbacks to eccentric training is overtraining (hence your warning about the time periods) and just safety (Which can be taken care of if you do them on machines)?
Why don't I see more people doing eccentric training?
