Safety: Lightweight bench that is easy to lift. Button can be pressed easily with foot to bring the bench back down, unlike other benches that have a bar that needs lifted with the hand not holding the bench.
Balance: Weighted backpack-like tool that measures the center of balance of the user. Connects to a watch/smartphone that allows them to know which way they should lean to correct their balance.
Bar Exercises: Machine with bars attached so they are hanging down. Allows a one armed user to use dumbbells/weights in a safer way that mimics the use of two hands. If the machine notices struggling by the user, the pulley can lift the bar away from the user.
