HIIT or high-intensity interval training has been used in athletic populations for a long time, but has recently come into vogue with almost every other demographic ( including cardiac patients!)
Intervals involves performing work bouts that are separated by passive or active rest periods.
Progress can be made by changing one of the following:
Duration/distance of work interval
Intensity of the work interval
Duration of the recovery interval
Number of work intervals (repetitions)
Number of sets of intervals
Generally a work-to-recovery ratio is 2:1 for short intervals (60 seconds or less) or 1:1 for longer duration intervals. Your heart rate should fall to 100-110 BPM before the next work interval begins.
