CATI Armor Ergonomic Fitness Plates Review – Fitness Test Lab
CATI Ergonomic Fitness Plates came onto my radar when I was researching options for this article.
Unlike companies who are primarily fitness gear providers, CATI makes
ballistic armor designed to be worn close to the body for long periods
of time.
As a result, they have
lots
of experience with ergonomics, so developing an ergonomic fitness plate was a natural extension.
You might be wondering what I mean by an ‘ergonomic’ plate. Until
very recently, most weight plates designed for fitness were flat slabs
of metal.
Flat plates work okay for fitness purposes, but since they don’t conform to the body they tend to limit mobility of the wearer.
The
CATI Ergonomic Fitness Plates
are different in that they are curved in multiple places to conform to
your body, resulting in a more secure and snug fit.
Combined with the swimmer’s cut, these plates are hands down the best
plate option for adding weight without restricting mobility.
These plates are so good that I’m sure it’s just a matter of time
before the broader fitness industry moves away from flat plates entirely
and toward multi-curved plates.
