Fartlek Drill - Speed Play Interval Training!

Fartlek, which means speed play in Swedish, is a form of interval training that uses the bodys energy systems at different intensities and time periods, varying and alternating frequently. This puts the bodys energy systems under acyclic stress, better mimicking sports specific energy demands. For more information about the bodys energy systems and aerobic and anaerobic fitness, maximum oxygen uptake (VO2max), training concepts and other useful information, please visit the pages in our Support section of our Website.
