Chairs are so passé. “It’s all about the ball!” says Technogym personal trainer Josh Holland. Behind every desk at the company’s headquarters in Cesena, Italy, is a Wellness Ball, a chic version of the ubiquitous PVC inflatables found in gyms around the world. Besides its cool look, what makes the Italian model extra special is the dual-lining cover of breathable honeycomb material, similar to running shoes, and the dense lower half, which allows for more control. It also comes with a QR code to access video training programs and a dedicated website for health and fitness tips. When we tried out the ball during a visit to Technogym’s campus, we immediately wanted to bring one back; after all, who doesn’t need help correcting one’s posture, improving flexibility and toning abs and legs? Now it’s available stateside in 21- and 25-inch sizes. $225 each; 70 Greene St., New York; technogym.com.
