As many of you know, Greg Everett has opened his new facility in Sunnyvale. Greg posted a video of the inaugural workout on January 27 on his Performance Menu site that I think is worth watching because it has many of the lifts that we did last weekend. In particular, note how close they keep their feet to the ground when they move from the jumping to the landing position.
Also for those of you that are keeping track of the high bar vs low bar squat “debate,” I found these two great links on the performance menu forum:
High- and low-bar squatting techniques during weight-training
Eight Swedish national class weightlifters performed high-bar squats and six national class powerlifters performed low-bar squats, with a barbell weight of 65% of their 1 RM, and to parallel- and a deep-squatting depth. Ground reaction forces were measured with a Kistler piezo-electric force platform and motion was analyzed from a video record of the squats…
I will try to get a copy of this article.
Extremely thorough post by Glenn Pendlay on CrossFit.com forum
“So much has been said here, but I have a couple of observations that (I think) haven’t been made…
There is the assumption that high bar squats, done very deep, do not work the posterior chain. I would propose that they do, and the difference between high bar and low bar and the posterior chain is not as large as some would assume it is.”

See you this Saturday!
The torque and shear forces are slightly less w/ low bar squats because the bar is closer to the hips; low bar squats have a shorter lever arm from load to hip.
So I think of low bar squats as being slightly safer for the back than high bar squats at the same load.
OK. I just read the summary of the first article. I don’t completely understand how test was conducted, how adjustments, if any, were made for size differences amoung the lifters, what controls were used, etc. And the sample size is very small. So… not sure what to conclude from the first article other than that some guys played around with a force plate and some computer software.
Yeah, I am going to have to get the article at some point in the near future. That they wrote software to analyze the data made me more than a little suspicious.
