I've heard that Jerk from behind the neck are supposed to be stronger than from the rack position, but the idea of having to get the weight over my head in order to bail makes me nervous. How strongly is the behind the neck position recommended? |

It's a much more secure platform and reduces the moment on the hip and upper back, so the forward leaning often seen in jerking is easier to resist. Also, the bar can travel in a perfectly vertical line to the overhead position. This is why it typically allows more weight to be handled than from the front. Start light and feel it out. If you get to a point at which you're too uncomfortable to continue, switch to the front. But guaranteed if you're having any trouble from the back, it's because you're dropping the chest and pushing the hips back. Ensure a straight dip and drive and you'll be fine. |

Check out the "Quest for 300 overhead"
"http://media.crossfit.com/cf-video/CrossFit_300.mov"
video over on crossfit"
It shows how the one guy has more power from behind the neck.
You could also go here and look under misc. videos if you want to open it in windows media player.

Greg,
Can you describe to me the Dip/Drive? I was thinking that you had to put your hips back like when doing squats and not push the knees forward. This was after reading the "muted hip function" article on crossfit. Am I now dip/driving wrong? Any vids I could watch to see the specifics.

The dip/drive of the jerk is identical whether in front or back - the hips travel straight down and up - no rearward travel. With the bar in the back, the torso will have to be leaned forward slightly to keep the bar balanced over the foot, but this angle should not change as you dip and drive. In other words, in the front, the shoulders, hips and ankles should remain in a vertical line throughout the dip/drive; from the back, it will be more like the bar, hips and ankles in that line. |

Thanks Greatly.
I mis-interpreted the MHF article. My drive has been feeling much weaker with more pressure/torque being applied to my core since I changed. A Big difference from the power squat where the knees stay stationary in the beginning of the movemnent. I will correct this in my son's form also.
Why does Glassman say during the end of a 20r PJ he can tell in the first 1/10th of a second wether or not the athlete is starting to fatigue and getting MHF?

When you are going for the heavy single, I am assuming you are working your way up to that weight at your own desired pace in terms of the load increase. Once you reach that heavy single, do you just do one rep or should you do multiples? |

Prochargedmopar -
I imagine Glassman is simply watching the hips - a correct dip will have the pelvis remain neutral and the hips dip vertically; MHF will have the hips slide forward and possible the pelvis rotate posteriorly. Nothing magic about recognizing it; you just have to be paying attention.
Pie -
Work your way up however you want to the heaviest rep you can manage. If it's really the heaviest rep you can manage, you won't be able to do multiples. |
