Activate your core musculature and build up your balance with an MD Buddy Anti-burst Stability Exercise Ball – available in 75 cm. Rolling unpredictably, a stability exercise ball forces you to keep your ab, leg, back and upper body muscles in constant motion. You’ll be rewarded for that effort with improved posture and greater flexibility and increased overall strength and fitness. It’s the perfect accessory for yoga and pilates, not to mention body-defining exercises like knee tucks, glute bridges, push-ups roll outs, Russian twists, and planks. These balls are easily inflated and can safely handle your full, active weight– thanks to its durable, anti-burst, abrasion-resistant, and highly elastic exterior. Deflated, they’re light and portable so you can take them with you anywhere.
