A Tempo Trainer is a small, waterproof device that emits beeps at regular intervals. These beeps act as timing cues, helping you maintain a steady pace during your workout. Athletes often attach it to their goggles, swim caps, or clothing, depending on the sport. The device can be adjusted to suit your training needs—whether you want to improve your stroke rate, running cadence, or cycling rhythm. For example, swimmers use the Tempo Trainer to control their stroke tempo. If the device beeps every 1.2 seconds, the swimmer aims to take one stroke with each beep. This helps maintain consistency and efficiency in the water. Similarly, runners use it to control stride frequency, ensuring that each step matches the rhythm. Cyclists and rowers also find it helpful for maintaining a smooth, consistent motion.
