Add a new balance training challenge to your fitness regimen with the Cathe Balance Disc. This 14-inch anti-burst, inflatable wobble disc can be used for a variety of seated and standing exercises to create balance challenges while improving core strength and body posture. The Cathe Balance Disc can assist in improving balance, flexibility, and overall strength and stability when incorporated into a fitness routine. The disc can be inflated and deflated to different levels of firmness depending on your comfort and the level of challenge you're looking to add. The Cathe Balance Disc can also be used as a seat cushion or a wiggle seat when you're not working out. This type of cushion increases core awareness and strength while sitting, similarly to that of sitting on a stability ball. Sitting on this type of wobble cushion disc can also help to take pressure off the back and shoulders to help alleviate aches when sitting for long periods of time.
