You may have seen them in the gym: half of a large rubber ball that’s flat on one side. They’re often blue in color and look like a gigantic outtie belly button. “What are those things?” you wonder. Well they’re BOSU balls (or balance trainers). It’s the latest rave to hit fitness centers across America.
BOSU is an acronym that stands for “Both Sides Up”. You can use the balls, also referred to as trainers, or balance trainers, on either side. Whether the rounded bouncy dome part is up or the flat 25 inch platform side is up, you’ll get different types of balance challenges.
This cross-training fitness invention has its origins in the field of medicine, balance, functional and sports specific training. It offers a different means to make exercise more appealing and effective for average people, fitness fanatics and highly trained athletes.
So what do you do with it? You can walk, run, step, hop, jump and leap on the BOSU trainer. You can work it at an easy steady rate-pace that can be maintained for long periods or push the intensity with anaerobic intervals. Or do some stretching on it.
