BOSU trainers

A BOSU trainer is a piece of fitness equipment used for balance, stability, and functional training. It looks like a half exercise ball attached to a flat platform.

The name comes from “Both Sides Up”, meaning you can use it two ways:

• Dome side up → for balance exercises (like squats, lunges, core work)
• Platform side up → for stability and strength challenges (like push-ups or planks)

The most well-known version is the BOSU Balance Trainer.
