Business trips don't set back our training: We pack along the Hyperice Normatec Go to keep our legs primed for tempo runs and sprint repeats. These wearables use air compression to massage our calves, reducing swelling, relieving tension, and increasing circulation. The sleek, wireless design slides easily under trousers and operates quietly for discreet use in the office and on long flights, while the built-in, rechargeable control units provide up to 3 hours of massage on a single charge.
