"The method thereby relies on 'the anaerobic energy releasing system almost maximally'."

Tabata: A type of HIIT workout that involves 20 seconds of high-intensity work followed by 10 seconds of rest, repeated for eight rounds total.
AMRAP (As Many Rounds As Possible): A CrossFit workout where you perform as many rounds of a set series of exercises as you can within a specific period.
EMOM (Every Minute On the Minute): A workout that involves performing a certain number of reps of a specific exercise at the start of every minute, and then resting until the start of the next minute.
Cindy: A CrossFit workout that consists of five pull-ups, ten push-ups, and 15 air squats, repeated for as many rounds as possible within a set time frame.
The 300 Workout: A grueling CrossFit-style workout inspired by the movie "300," consisting of a series of exercises performed in rapid succession, such as pull-ups, push-ups, and deadlifts.
Interval Training: A type of HIIT that involves alternating periods of high-intensity work with periods of rest or low-intensity exercise.
The Murph: A challenging CrossFit workout that consists of a one-mile run, 100 pull-ups, 200 push-ups, 300 air squats, followed by another one-mile run.
"The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic (cardiovascular) activity."
"...maximal effort, duration, and short rest periods (thereby triggering the anaerobic pathways of energy production) materially differentiate it from being considered a form of cardiovascular exercise."
"A HIIT workout typically lasts under 30 minutes in total... The times vary, based on a participant's current fitness level."
"Intervals of exercise effort tend to range from 20 to 45 seconds but no longer than 75 seconds."
"HIIT workouts provide improved athletic capacity and condition as well as improved glucose metabolism."
"Compared with longer sessions typical of other regimens, HIIT may not be as effective for treating hyperlipidemia and obesity, or improving muscle and bone mass."
"Research has shown that HIIT regimens produced reductions in the fat mass of the whole-body in young women comparable to prolonged moderate-intensity continuous training (MICT)."
"Sprint interval training (SIT) is an exercise conducted in a similar way to HIIT, but instead of using 'near maximal' effort for the high-intensity periods, 'supramaximal' or 'all-out' efforts are used in shorter bursts."
""Near maximal" means reaching 80–100% HRmax."
"SIT regimens generally include a lower volume of total exercise compared with HIIT ones as well as longer, lower activity recovery periods and creates a greater homeostatic disturbance."
"Both HIIT and SIT fall into the larger class of interval training."
"Distinction between the two is not always maintained, even in academia."
"Traditional HIIT initially had been designed to be no longer than 20 seconds on with no more than 10 seconds off."
"Some researchers also note that HIIT requires 'an extremely high level of subject motivation' and question whether the general population could safely or practically tolerate the extreme nature of the exercise regimen."
"HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The body significantly recruits anaerobic energy systems (although not completely to the exclusion of aerobic pathways)."
"HIIT workouts provide... improved glucose metabolism."
"HIIT's crucial features of maximal effort, duration, and short rest periods materially differentiate it from being considered a form of cardiovascular exercise."
"HIIT workouts provide improved athletic capacity and condition."
"Though there is no universal HIIT session duration, a HIIT workout typically lasts under 30 minutes in total."
