About Interval Run: Treadmill Coach
Exercise healthily, backed by science. Doing intervals on your own usually means watching the clock more than the run. Every minute you have to speed up, change the incline and remember what comes next. Interval Run does that part for you, by voice. Put your earbuds in and just follow what you hear. [Treadmill mode] It tells you ahead of time when to change, to what speed and to what incline. It even allows for the few seconds your belt needs to catch up, so each change is called early and you hit the new pace right as the phase starts. [Outdoor mode] Outside, GPS tracks your distance and pace. Drift below your target and the coach says "a little faster", so there is no need to pull out your phone. Every run is saved with its route on a map. [14 proven interval programs] Both modes use the same programs, from walking to sprints. Pick the one that fits where you are today. - Beginner: Run-Walk, Power Walk, Slow Jogging, Easy Run - Intermediate: Lose Weight, Endurance, Tempo, Pyramid, Fartlek, Hill Repeats, Legs Strengthening - Advanced: 4 × 4 Intervals, Hill Sprints, Agility Booster
