Vibrating massage ball

Try this

The Hyperice Hypersphere (£139.95, live-on-the-edge.com) is a firm massage ball that promises to get deeper into soft tissues by combining soft-tissue therapy with high-intensity vibration. It can be used to prime muscles for warm-up or assist recovery. It has three speeds – the top one intense enough to send the ball skittering all over the floor. It’s rechargeable, with two hours’ use per charge.
