When not running my software biz, I make exercise machines which use flywheels for resistance. The difference compared to traditional weights is you get constant resistance at all angles throughout the entire range of movement.

It also includes an app + sensor (Electronic hardware is a complete PIA, but we got there in the end) https://exerflysport.com https://exerflysport.com
