I read Dewey Nielsen's article and I have to say that it is VERY uninformed.
I am by no means a "cool-aid" drinker. I did CF for about 2 years but quit due to cost and I didn't feel that the gym I was at was a great example of CF. I have my disagreements with the CF methodology and mentality but I do feel like it is a great way to get in shape.
This quote in particular is very uneducated:
Everything should be scaleable. Simple to complex movements. Lighter weight to heavier weight. Slower tempos to faster tempos. Common sense stuff. But this is exactly what Crossfit lacks. There is no progression. Everybody does the same exercise, with the same load, for the same reps with absolutely no respect to form and technique. Get it up with any means necessary. But I’m sorry for the common sense here….. If Jane Doe can’t front squat 115 lbs for 1 rep, then she can’t front squat 115 lbs for 20 reps. Now, before the Crossfit community starts calling me a pussy and sending me death threats, I can comfortably say I am not.
If Mr. Nielsen ever walked into a CrossFit gym he would see very few individuals doing the workout as prescribed. Most, sometimes all, would be scaling either the weight...the number of reps...or both. Some of the newest members might even be using no, or extremely low, weight; especially during Olympic lifts.
I do agree that it is FAR to easy to get a certification and open a gym. This is by far my biggest gripe with CF. There is HUGE variation between gyms. If you get a good one, they will make sure your form is perfect before you even get to use weights. If you get a bad one...it becomes a dangerous extreme sport!
