The Exer-Genie!

by | Sep 25, 2023

The Exer-Genie was an isokinetic device, roughly the size of a television remote control, consisting of a friction brake, a 10 foot length of rope, and a loop on the back end to secure it to something immobile.

Since resistance came from friction, and not dependent on gravity, as the story goes, The Exer-Genie was developed for the astronauts to utilize in space during the Apollo and Skylab missions of the 1960”s and 70’s (The Exer-Genie was also marketed under the name “The Apollo Exerciser” to capitalize on this phenomenon.)

Gym teachers and sport coaches loved the Exer-Genie because it was small and cheap, hence large groups of athletes could train with a bunch of them at once and go through a full workout quickly. As you can see in the advertisement above, a major selling point to sport coaches was to mimic athletic movements with resistance added by

The Exer-Genie with the goal of improving sporting ability in running, jumping, swinging a bat or racket, etc and other specific skills. The Green Bay Packers were one of the first professional sports steams to utilize the Exer-Genie and within a few years, many other pro sports teams followed suit.

Evidently, The Exer-Genie is still going strong today!
