Fartlek, which means "speed play" in Swedish, is a form of interval training that uses the body's energy systems at different intensities and time periods, varying and alternating frequently. This puts the body’s energy systems under acyclic stress, better mimicking sports specific energy demands.

With the FartlekDrill App you can train in several modes making each Fartlek drill different. You can either quickly select a drill based on an intensity level and sport or customize the drill in detail to better suit your training needs.

This app is available in a sale bundle with our AeroExaminer App, allowing you about 25% savings when compared to purchasing separately.

The Fartlek App has a “random” mode, in which the engine generates the number of stages, intensities and times based on a sport or your own time distribution (percentages) scheme, and a given intensity.

You can also configure manually each stage’s intensity and time period. You can combine random and manual effects, making this App fairly versatile to adapt to your needs.

Using the In-App Upgrades you can upgrade the App to include the Sports Zoning Module. This module allows you to configure a time distribution scheme, save it as a sport and use it in any Fartlek Drill as you use the default sports.

Also, with the In-App you can add the features of our popular AeroRadar App to help you plan and set your training objectives.
