Adidas was one of the first to the fitness-monitoring market, and the SpeedCell is still the best all-around device. An accelerometer that you embed in the sole of your Adidas shoe (or clip to the laces of your regular kicks) tracks speed, sprints, intensity, number of steps, and stride length, among other factors. After a workout, the SpeedCell connects wirelessly via USB adapter or iPhone dock connector and uploads your data to your computer and to the company’s online MiCoach app, then spits out a comprehensive digital chart of your performance. There are nine training packages (women’s and men’s fitness, running, football, soccer, rugby, etc.), and the app can tailor each of them to your goals based on your initial stats. The quantity of data can be overwhelming at first, but once you understand what you’re looking at, achieving your fitness objectives is as simple as following instructions.
