Product Feature: On the Ball

Work the deep stabilizers, protect the spine and prevent back pain with a Stability Ball™. Different size balls work for different heights and exercise purposes and help build core strength, improve posture and muscle tone. Stability Balls are also perfect for stretching post-workout, increasing flexibility and reducing soreness.

Made of anti-burst material, Merrithew Stability Balls can take weights up to 550 lbs, and can be used across a variety of fitness modalities, from athletic performance training to Mat classes. Use the smaller Stability Balls to challenge balance and proprioception in a range of exercises and modifications.

Add a base to a Stability Ball and turn it into an active seat to use in your home or work space to challenge your core while you read through emails or watch TV.
