High-Intensity Workouts May Keep People Coming Back
Irregular Exercisers Find HIIT Enjoyable

Researchers divided 40 sedentary, healthy adults into two groups. One participated in HIIT, which consists of short bursts of intense exercises, followed by lower-intensity recovery periods, for six weeks; the other group performed ongoing moderate exercises. The researchers discovered that while both groups started out with equal enjoyment levels, the HIIT group enjoyed their workouts more as they gained strength, while the moderate group reported unchanged or decreased enjoyment levels.
