The MANTRA SPORTS Exercise Ball is a gym-grade stability ball made for real daily use—yoga, Pilates, fitness workouts, core training, balance exercises, stretching, mobility work, and physical therapy. It’s also a popular choice as a pregnancy ball, birthing ball, and labor ball for gentle movement, pelvic mobility, and comfort at home. Whether you’re building strength, improving posture, or adding variety to your routine, this workout ball helps you train with more control and confidence. Built to support up to 330 lbs, this anti-burst exercise ball is designed to resist sudden popping and release air more slowly if punctured. The anti-slip textured finish helps reduce sliding on the floor and improves grip against your body—use it for ab exercises, back support, stability training, flexibility work, and rehab movements. Many customers also use it as an exercise ball chair, desk ball, or sitting ball for active sitting at work to engage the core and support posture during long desk hours. This versatile gym ball / physio ball / therapy ball works great for a home gym setup, studio workouts, recovery routines, and pregnancy use. It’s ideal for anyone looking for an inflatable exercise ball that can handle strength and stability work while staying comfortable for stretching and sitting. Every set includes an air pump, plugs, and easy instructions so you can set up quickly and get started right away. (See listing images for the exercise ball size guide and the step-by-step inflation guide.)
Anti-burst, slow-deflate performance: Thick, durable PVC engineered to release air gradually if pierced for a steadier feel during movement. The lightly textured, non-slip surface keeps the exercise ball / yoga ball / gym ball / physio ball stable on smooth floors, so you can focus on reps—not on readjusting. Material is BPA- and heavy-metal-free and designed for everyday home workouts.
Versatile training & posture support: Build core strength, balance and mobility with a single tool—perfect for Pilates, yoga, stretching, ab work and stability drills. Between sessions, use it as an occasional desk-sitting alternative to promote active posture and gentle engagement of the trunk muscles. It’s the multifunctional Swiss/stability ball your routine was missing.
Confident grip & control: Subtle concentric grip lines help prevent sliding while you bridge, roll-out, or perform dumbbell moves on the ball. The matte finish feels secure under the hands, forearms and back, giving you smooth, predictable feedback through each range of motion—ideal for beginners and seasoned home athletes alike.
Easy inflation & included accessories: Everything you need is in the box—hand pump, 2 valve plugs, plug remover and measuring tape—so you can inflate to the target diameter, let the material settle for 24–48 hours, then top up to final size for best shape retention. Clear quick-start guidance gets you training in minutes.
