History
I thought of designing a machine to measure isometrics during the summer of 2005. It was motivated by a desire to become
stronger. By supplementing and by using isometrics, I achieved my goal. I wanted measurable isometrics, so I improvised using
a bathroom scale while sandwiching myself between door jambs. However, there were problems:
- The distance between myself and the scale between door jambs was not adjustable
- Exercising the legs between door jambs was not practical
- I was exceeding the scale capacity of 120 kg
(264 lbs)
All of these drawbacks were solved by creating ChainExerciser.
