ProBody Pilates Stability Trainer Yoga & Exercise Ball

From The Manufacturer

The professional-grade ProBody Balance Balls come in 45, 55, 65, 75 and 85 cm diameters and are designed with thick, burst-proof walls for ultimate support and durability. The chosen material is 6P free and does not have the well-known harmful phthalates. Take control and meet your fitness goals without expensive exercise equipment. Using a stability ball will improve the strength of your abs and lower back. Since a Yoga ball is unstable, you have to use your body’s core strength to remain balanced, which in turn improves proprioception, flexibility and body alignment.
