Reading "Explosiving liftign for Sports" by Harvey Newton. Really like his intro about the different strength and conditioning camps and their views on O-lifting.
In his intro to the snatch technique, he recommends lifters not to leave the ground during the third pull. If you are airborne, you can't actively pull yourself under the bar. How do you move the feet out if you don't leave the ground? Also, some lifters seem to do just fine pulling under with their feet off the ground...or it seems they have managed to flex their hips, knees, and ankles almost into a deep squat before they remake contact with the ground.
Anybody snatch here without leaving the ground? |

That line right there is one of the reasons I don't like that book. I'd like to give Newton the benefit of the doubt a chalk that statement--which, as I recall, he makes twice--to an editing error, but it makes no sense at all. Technically the feet do not have to leave the ground at any time during the snatch or clean - all that must occur is a reduction in force against the ground sufficient enough that it doesn't prevent the attempt to pull on barbell's inertia in mid-air from creating rapid enough downward acceleration of the athlete. In other words, contact is irrelevant in regards to the physics of the movement--pressure is the key.
That said, if you subscribe to the notion that the athlete can best pull from one stance and best receive from a different stance (which I do), the feet must be transitioned between the upward acceleration of the bar and its receipt. In the time frame available, this can only be accomplished by a loss of contact between that feet and platform.
I just double checked the book before I signed the deal - "This maneuver [pull under]... can only be accomplished with your feet on the floor" is the quote from pg 47.
If anyone can explain the physics of this to me, I'd be much obliged. The pull under the bar is achieved through the effort of the lifter to pull on the bar while NOT applying force against the ground--this lack of force against the ground makes the barbell an anchor around which the athlete moves. The greater the mass of the barbell relative to the the athlete, the farther the athlete will move relative to the bar as a result of this effort (assuming constant force).
Bottom line being, no, you don't have to remove your feet from the platform to pull under the bar--but to stay that you CANNOT remove them makes no sense. |

Rob does not appear to be convincing me of anything! I will not have his "dancing". OMG that pic makes me laugh. |

The sled in the video, homemade or purchased?
Thanks.
Eva, wise move passing on the dance partner. Once that stuff gets up on the web, hard to live down or deny. |

Josh -
That workout isn't meant to be done today - This is a rest day. It's just a sample workout. |
