The Nexus Package ($299) is a great gift for those who love CrossFit. According to the brand's website, the push band, arm strap, and compression sleeve was designed to "truly track and share performance." According to Gear Patrol, "The band watches your movement patterns as you move from squats and lunges to box jumps and jumping jacks. It also counts your reps as well as your velocity, displacement, power, and time." Gear Patrol also reported that the Nexus tracks recovery time and intensity of the workout and lets you know areas within a workout that need improvement.
