1. Anti-slip: The fitness ball is made of frosted material, which can effectively increase friction. This stability ball ensures a proper and safe grip when used for exercise, back support, or as a birthing ball during pregnancy. Focus on targeting thighs, glutes, abs, pelvic floor, and other muscle groups. 2. Multi-purpose use: The fitness ball helps improve core strength and flexibility. It can be used for exercise, as a yoga ball chair in home offices or classrooms, and also serves as a labor or pregnancy support ball. 3. Manual inflator pump included: This exercise ball comes with a hand pump for quick and easy inflation. The ball arrives partially deflated for convenient setup. Inflate within minutes. Note that the durable material may create resistance during initial inflation. Continue inflating as needed—it will become easier with use. 4. Maintenance: Wipe clean and store in a dry, well-ventilated area. Avoid using strongly acidic or alkaline cleaners. Do not expose to direct sunlight or high temperatures.
