Katalyst

The katalyst is a device that helps injured athletes or just normal people work out without strain. It's features are a four piece set (or more) that helps people in need. This suit is special because the suit has 26 electrodes strategically mapped to all your major muscle groups so you can effortlessly workout without pain reinjuring yourself. 

This is an improvement because it makes doing a full body workout possible in just about 20 minutes.  Then more importantly it works with paralyzed people or severely injured individuals to make sure they can still work out if they want to. They have different workout equipment based on the needs of the buyer including people with less mobility. So they do not have to lift weights because there are none for no pain.
