Impressive lift, indeed. But four big wheels on each side + olympic bar = 405 lbs. But a far cry from 585 which is six plates on each side.

As I figured. I assumed she might be able to do it with the assistance if a power rack or even a smith machine. Not the same as a true dead.  She's completing the last six inches of the lift. It's a nice trick for upping your max but not an honest-to-goodness deadlift which starts with the weight on the floor.   

I used to lift quite a bit and am familiar with many techniques and theory. The idea behind this is that by completing "partial" reps through the strongest segment of the lift (usually the top portion of the rep) using much more weight than you can use through the entire range of motion, you build strength and increase the amount you can lift through the entire range of motion. I'm sure Belle is trying to increase the ammount of weight she can lift in a full range of motion deadlift. Then the next time she deadlifts, she can use this increased strength to do full range reps with more weight which, in turn, results in shocking the muscle into new growth. Imagine that - an even BIGGER Belle. I, for one, am all for it. It's basicly a shock technique to blast through a plateau when your gains have stalled or stopped using conventional lifting.

In a nutshell, heavy patials develop strength which is then used to build mass. The power rack is perfect for this. You can place the bars at whatever height you wish and complete reps with heavy weight at the top postion of the lift for all the power lifts - deads, squats, or bench press. I've done it and it works.     

I've missed your explanation. ok, now I see. I just haven't seen anyone doing that, I just seen high deadlifts like this one. High but not that high as Isabella does.
