The person is strapped into the flexible chamber, it's enclosed and inflated with air. By increasing the pressure in the chamber, it lightens the load of the person's weight on the legs, simulating less gravity. It allows you to jog or walk without having to bear 100% of your weight.

At least that's my basic understanding.

I don't think you have a basic understanding at all.  What you have, sir, is a complete understanding.
