I was wondering if hammer strength machines shared a similar variable resistance that made nautilus unique.
Yes, Hammer machines are similar to Nautilus.
Didn’t Gary Jones, Arthur’s son , work on Hammer machines? Scott
Yes he designed them. Just wasn’t sure how far the apple fell from the tree. Lol
I think one of Gary Jones’ main innovations was to use a 4-bar linkage instead of a cam to vary the resistance. It gets rid of issues related to cable or chain friction and stretch. If memory serves me, I think some of the MedX machines (leg press at least) used a 4 bar linkage instead of a cam.
