Made famous by Mr. Tabata but developed by the Japanese Speed Skating Coach, this type of training uses short periods of intense exercise followed by a short rest period of half the work interval. Famously, 20 seconds work, 10 seconds rest. The Tabata protocol is then cycled a number of times, usually 4-8. Tabata Interval Training has been proven to increase your Aerobic and Anaerobic threshold much quicker than steady state cardio lasting 60 minutes.
