Mark Rippetoe said:They remove the stretch reflex from the bottom of the squat, and thereby make the squat about twice as hard - so you have to use about 40% less weight on the bar, depending on where the depth is set.
They are harder cause somebody put a damn box in the way!
Ha ha ha ha - what sort of bastard would do that.
My box is a good 20kg higher than my free squat to same depth. It's probably, like everything, an individual thing. Most of the research I've seen on pro athletes (ie not lifters) have their box squat significantly higher than their squat (5-10%) example using rugby player means
Locks n=121 Box= 157 Free= 141
Inside backs n=212 Box= 155 Free= 141
Centres n=58 Box= 163 Free= 151
Outside backs n=172 Box= 157 Free= 145
hmm... so maybe my 70KG's feels heavier because i'm stopping at the bottom trying to get depth...
I don't actually have a box, I'm just pausing a lot at the bottom while i try to find my depth and stretch....

If you box squat more than you free squat it's because your box is set too high, your free squat sucks anus or your name is Chuck Vogelpohl
I want to try these now to see how much I can box squat.
How would these help in powerlifting?
