I find smith machines as useless as the next man, so I was pretty pissed when my gym plopped down a few g’s to buy a shiny new one last week. But this one is different. The bar moves three dimensionally so that the usual smith machine problems of forcing the user to move the bar in an unnatural motion and not stabilize the weight are no longer present.
I refuse to let my gym off that easily. There must still be something wrong with 3-D smith machines, right?
Charles Poliquin actually likes this machine. Although is it really 3D? The normal smith machine is only 1D. As far as I know, this particular smith machine can move up, down, forward and back, but not side to side, which makes it 2D. I could be wrong, though…

That’s only 2D. You can’t go left and right with that thing, only up, down, front and back. I can’t believe they call their product 3D when it isn’t.
It pretty much takes out the lateral component of balancing out of the lifter. This is what’s wrong with that smith machine.
However, it’s a lot better than an ordinary smith machine. 2D is better than 1D hands down. I wouldn’t be too pissed about it.[/quote]
This was the first thing that came into my mind - the machine can’t be 3-D. The only 3-D machines I know of are free weights and bands/chains.
I lift in a max-rack/3d smith (the only rack my gym has).
Well it’s not like a smith AT ALL. I can’t squat in a smith, its like a different movement, BUT squatting in this weird rack , is like free weights… and it has 100% carryover. It’s completely the same thing.
So if its the only rack your gym has, use it. You ll not be missing out on anything!

Yeah, looks ok I guess. I’d prefer to see you get all psyched for a free bar without a bad on it.
As graphicsMan correctly mentions, a free bar has 5 degrees of freedom, while this “3-D” rack allows only 2 degrees of freedom. You get robbed of 3 :).
