Pair of PurAthletics toning Balls

Two blue PurAthletics massage balls. Each ball is approximately 6 cm or 2.36 inches in diameter. Approximately 3 pds each. Design & Feel: A soft, sand-filled mini fitness ball designed primarily for Pilates, barre, and low-impact resistance workouts. Unlike bouncy playground balls, it absorbs impact and sits heavily in the palm of your hand to prevent slipping during sweaty routines. Primary Use: Used in Pilates and core training to add slight upper-body resistance, or placed between the thighs or ankles to engage deep stabilizer muscles.
