By easier I mean which should you be able to do more weight on.
From what I understand and have been told the power clean should allow for a heavier lift. However I can hang clean much more than I can power clean. Does it vary athlete to athlete? Or is their probably something wrong with the way I power clean?
I'm not oly lifting expert, but my understanding is that the 'hang' referes to the position in which you BEGIN the lift (ie bar by the knees) and 'power' refers to where you catch the bar (ie in a quarter/half squat as opposed to a full squat.) So they're not mutually exclusive - you can do power cleans from the hang position.
I think that you mean you can hang clean more than you can clean from the floor - but I hesitate to offer an opinion based on an uncertain conjecture
The word power is generally used to describe the catching position, not the starting position. Basically if you catch the bar above parallel it is termed a power clean whereas if you catch it below parallel it is termed a squat clean.
If you regularly train both lifts, I think it's pretty clear that the lift from the floor should be the stronger one, due to added momentum and the fact that you should be able to deadlift more than you can hang clean anyway, so the lower portion wouldn't be detrimental to the lift.
It's about on par with asking what should be heavier, strict military presses or push presses? With push presses, you use leg drive to get more momentum and your squat should be more than your military press, so the lower portion wouldn't be detrimental to the lift, once again.
I'm not trying to boast when I say this, but I'm pretty sure my legs aren't whats holding my clean from floor back. I don't know my one rep max, but I can full ATG squat 350 x 5. I know thats not huge numbers, but I also know its not bad for someone of my weight.
There really shouldn't be much difference between a power clean and a hang power clean. If your technique from the floor to where the bar is at mid-thigh is improper, then you will probably lift a heavier weight from the hang. Of course, if you have a weak grip and are not using staps and doing several reps in a set you might find that your hang power clean is less than your lift from the floor. Bob Takano
Another way to look at the issue is ask what are the world records for the two lifts?
I don't have anything definitive, but I know that the Iranian super heavyweight did a Clean & Jerk of 580 in the 2004 Olympics, so we know a Clean of 580 is possible. But what's the most you've ever seen someone Hang Clean? I can only recall a video of 400.
