And Don is right that when you and the bar are in the air, you can’t exert any force on the bar and you can’t exert any force to pull yourself under the bar. At that point you and the bar are just floating in space in a low earth orbit. Don is correct that there is no reason to leave the ground. All you need to do is break contact so you can shift your feet out a little wider to get a wider base to get into a squat to receive the bar.[/quote]
This is something I’ve never understood when people talk about it. Even if you are in the air, you absolutely can exert force on the bar and pull yourself underneath it. I think that time in the air is still wasted because you are no longer exerting meaningful upward acceleration, but you can still pull against the bar with your traps/arms and separate yourself from the bar in a downward direction.

Sort of. Remember that things change once the weight gets heavier. With just the bar, I could probably leap in the air as high as I could and snatch the bar overhead while still in the air. Couldn’t do that with even 50 kg. I agree that you can, to a point, pull yourself downward against the bar while off of the ground. At some point in its trajectory the bar becomes weightless and you then pull yourself down. But it’s not something I would encourage.
This is one of the reasons why I advise caution with playing with techniques such as starting with your shoulders behind the bar and jumping backwards to catch it. I can do all sorts of crazy stuff with light weight - not keeping the bar as close to the body as I should, jumping back, all not a problem with light weight. However, these problems become magnified almost exponentially with every additional 5 kg on the bar.
And this brings me back to my point about triple extension. Don’s main problem with it seems to be the part where you rise up on your toes (plantar flexion). But except for the guy who jumps back, he still believes in keeping the hips low, the shoulders over the bar, rebending of the knees (“the scoop”), and a strong trap shrug. These are all things taught with triple extension. And from my own experience, as the weight gets heavy, I have less and less plantar flexion to the point where I only break contact with the ground for a fraction of an inch to move my feet out to get a wider base. I sure as hell can’t get big air with 90 kg on the bar. So, the increase in weight corrects for what Don sees as a “flaw” in the triple extension technique. However, I maintain my original position that teaching the triple extension to include a full shrug and maximum plantar flexion makes for a good teaching tool and encourages lifters to finish the pull.
Just my opinion and I may be totally wrong.[/quote]
In response to Dr Manhattan I agree that it is definitely possible to pull yourself down while you and the bar are in the air however I think it comes down to a control thing. If your feet aren’t on the floor you have no place of reference to set yourself in the right place. You’re just pulling under the bar and so are probably more likely to catch in the wrong position. Not sure if that’s true or not but it seems to make logical sense to me
Also, if you think about total energy it doesn’t make sense to come off the ground. The goal is to exert as much force on the bar to drive it upwards. Coming too far off the ground could be showing a lack of ability to transfer the force you generate into the bar to lift it. If you pull with the same amount of force but one time you come 5cm off the ground (exaggerated I know) and the other time only come off for 1 cm (just to skip your feet out) the bar is going to go higher in the second example as more of the force is used lifting the bar than you.
What you have written Mike makes a lot of sense to me. Thanks for clearing up some stuff!
