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.
We all know proper hydration is a key component of good health. Yet none of our activity trackers let us keep track of it. Until now. The LVL Wearable Hydration Monitor uses red light technology that measures 10 times deeper into your body than the green lights commonly found in fitness trackers, letting it both measure hydration levels and grab hyper-accurate heart rate readings. It also tracks your activity, sleep, and mood, and thanks to a case created by frog design, it looks far better than you'd expect from a piece of medical-grade equipment.
Fitbit's original Charge quickly became it's most popular product. So the Fitbit Charge 2 has a lot to live up to. It does so by adding improvements like estimated VO2 Max readouts that leverage the continuous hear rate tracking, built-in guided breathing sessions to help you relax, sport-specific modes to track workouts like runs, weights, biking, and yoga, and an interval workout mode. It also links to your phone to add GPS data to your workouts, has a larger tap-sensitive display, and easily interchangeable bands to let you change the look as often as your clothes.
No one wants to go to the doctor's office every morning. With the Withings Body Cardio Scale, you get a lot of the same benefits without the hassle. This 0.7-inch piece of aluminum and glass can measure and analyze a host of data about your health, including weight, BMI, fat, muscle, water, and bone mass percentages, and standing heart rate. It's also the world's first home scale with the ability to measure Pulse Wave Velocity, a measurement of arterial stiffness and a key indicator of cardiovascular health. In other words, it can provide a very early warning if you're putting yourself at risk for maladies like hypertension, high cholesterol, organ failure, stroke, and heart attack, all without having to leave your house.
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.
