Here’s one from back in the day which is evidently making a comeback: the good old Functional Isometric Contraction Strength Builder. There were several different versions but they were basically all a flat piece of wood or metal, a handle, and a length of chain or rope, used for performing isometrics in various positions. This one came from Bob Hoffman and Muscletown, USA and had a nifty course to go with it. You’ll find several “primary document” courses on isometrics in The Iron League.
