Grenade Grips

Whether you've hit a wall in your workouts or just want to maximize the precious gym time you've carved out of your busy schedule, Grenade Grips can help. Designed to slip over the handle of your dumbbells, kettlebells, pull-up bars, or any other surface you grip during a workout, these circular add-ons force you to use both more and different muscles than you would with a traditional open-hand grip. The result is a more effective workout, whether you're doing crossfit, traditional weightlifting, or just body weight-reliant calisthenics.

  • Vi Artificial Intelligence Personal Trainer

    Working out with a personal trainer to guide you is generally better than going it alone. The Vi Artificial Intelligence Personal Trainer gives you the same benefits as a real trainer in a device that fits around your neck. Using sensors in the neckband, attached earphones, and your smartphone, it knows your elevation, heart rate, cadence, speed, and location, and gives you voice feedback as you workout. It also responds to your voice commands, and since the earbuds were developed in collaboration with Harman/Kardon, they sound great, too.
