Interval fitness training fuses short, fast, and labor-intensive exercises with slower, tamer drills at alternating bursts. Since duration plays a major role, timers are often used for guidance.

At a very low cost, you can have a timer that's specifically designed for interval training. Tabata Pro is a professional, full-featured interval training timer that you can have within the convenience of your mobile device. It features three programmable timers, customizable time settings, number of cycles, and number of tabatas, the option to activate screen flashes for visual signals, alerts that can be heard even over very loud music, a speaking coach, multi-tasking abilities, and more.
