fark me. $400 Surely there is some sort of clamp type attachment I could rig up. Hmm...
Dunno
Westside were noted as using similar techniques as far back as the 80s
No idea who originated the idea though
Are you interested in knowing?
I didn't know you were THAT old
In the vid of the guy floor pressing?
Overloads the top portion of the lift and theoretically produces a more consistent strength curve eg the resistance is least in the weakest position and greatest in the strongest
Sounds like Nautilus
Darkoz, it actually was Arthur Jones.
Around the late 40's I think 1948 where he welded hooks to a barbell and attached heavy chain for that purpose, as the bar rose the weight of the chain increased, wanting to increase the resistance in the strongest position.
Maybe grab one of those pull up bars from racks and weld post on the end for weights. Pretty ghetto though and you'll have to trust your welds.
