BOSU functional balance trainers have been around for about 20 years. This longevity means that these products really work! BOSU stands for Both Sides Up, or Both Sides Utilized, which describes how you can use this workout tool – flat side up or curved side up.
A lot of people only use BOSUs for crunches, but, with a little imagination, you can use one to work pretty much every muscle in your body.
Combine your BOSU with a Gymboss timer for a time-efficient workout that will improve your balance, strengthen your core, as well as burn fat, and tone your entire body.
