Aerobic Interval (AI) training has emerged as a viable alternative to traditional steady-state aerobic (SS) exercise, a long-standing staple for improving cardiovascular fitness. What AI offers over SS is the ability to introduce frequent changes in exercise intensity to increase the overall volume of overload before inducing fatigue (i.e., by allowing appropriate recoveries between work intervals).
