High-intensity interval training alternates short bursts of very intense exercise with brief recovery periods to generate rapid cardiovascular gains in limited time. Workouts can be built by combining common moves such as squats, push-ups and jumping jacks to create thousands of distinct routines. Exercise order and selection determine targeted muscle groups; full-body routines should include upper-body, core, legs and cardio components.
