Fartlek, which means "speed play" in Swedish, is a form of high intensity interval training in which you use the body's energy systems alternating intensities and time durations during the workout. This puts the body’s energy systems under a acyclic stress, better mimicking sports specific energy demands. The Quick Fartlek, a reduced version of our Fartlek Drill App, allows you to quickly train selecting a drill based on a training intensity level and a sport. The Quick Fartlek App runs in the “random” mode, in which the engine generates the number of stages, training intensities and times based on a sport and a training level. Using the In-App Upgrades you can upgrade the App to include all of the Fartlek Drill App features, including a Detail Setup, which allows you to fully customize and saver your own drills. Using the In-App Upgrades you can upgrade the App to include the Training Zones Module. This module allows you to configure a time distribution scheme and save it as a sport, which can be used it in any run as you use the default sports.
