Think of the Vyper as a foam-roller on steroids. A favorite warm-up tool of Naomi Osaka, the high-intensity vibrating core inside the polypropylene roller helps loosen muscles and increase flexibility and range of motion prior to or after a workout. There are three speeds—low, medium or high intensity—although you may never need more than first gear. Work on trouble spots, or use the accompanying Hyperice app to follow guided activation routines. With two hours of battery life on a charge, and at just three pounds and 19 inches in length, the roller makes for easy transport in most racquet bags. The Vyper 3.0 (pictured above) is also now available, with an updated contour design and motor. Either one makes a great addition to your fitness regimen.
