  There are definitely boxes who focus on good form, which is great (and should be the norm), but I think due to the fact that the Level 1 cert is so easy to get, the quality suffers in some gyms.

  > I believe it's a CrossFit thing. Based on this claim I assume also that Crossfit invented the barbell, the bumper plate and gravity. The sudden outburst of anecdotes about how your Crossfit gym rooly trooly emphasises form seems to have come after years of sustained criticism by strength coaches and Olympic weightlifting coaches. It's as simple as this: nobody -- not me, not you, not your coach, not the pros -- nobody can pump out high rep Oly movements without steady and ultimately dangerous degradation in form. The force plate studies, the EEG studies, the eyeballing of experienced coaches demonstrate over and over and over that it is a flat out stupid idea to do snatches or cleans for reps. And yet in Crossfit gyms everywhere, this idea of smashing out 20 clean & jerks still keeps getting circulated. You cannot do this and learn to do the movements precisely enough. You will only train yourselves to do it messily. Under heavy weights you will fuck up and injure yourself. Given that I love Oly lifting, I don't want people getting injured and then blaming the lifts, when they should be blaming a faulty training technique.

    I haven't done crossfit, but I am curious - what prevents you from doing 20 proper form clean & jerks if you lower the weight?

      It's the timing aspect, and it's particularly an issue with squats. Even at lower weight, it's far to easy to get your knees pushed forward or your back arched when trying to pump through them as fast as possible. I don't think anyone is saying that it's not possible, it's just much more likely that your average lifter is going to run into injury.

      Nervous system fatigue. The Olympic lifts require: 1. Precision. 2. Power. In that order. The problem is that the motions happen so fast that even at light weights you quickly deplete the central nervous system's ability to provide sharp signals. Ideally the signal conveyed to muscles looks like a square wave. However as repetitions mount, it becomes more and more to resemble noise, leading to sloppy form. Repetition is the basis of learning, especially for complex movement. If you are doing 20 reps, and 15 of them have degraded form, what will you wind up learning? And it doesn't help that the emphasis is doing the 20 reps in the minimum time possible, which discourages lifters from taking the time to set themselves in the correct position off the floor. The weight is almost, but not quite, irrelevant to my main point. My main point is that the body learns what you make it do. If you continue to work through degraded form you will only learn to make the lifts sloppily. As you increase the weight (Crossfit calls this "scaling the workout" as if they were the first to think of changing the weight on the bar), you will only increase your risk of injury.

    I completely agree about the Oly lifts. There isn't a bad exercise, just bad form.
