HIIT is often dismissed as being only for elite athletes. However, the basic concept of alternating high and lowintensity periods of exercise can be applied to almost any level of initial fitness.
As with any form of physical activity, there are potential benefits as well as certain limitations associated with interval training.
The “pros” include the fact that intervals are a potent training stimulus, and even though the total amount of exercise performed can be quite small, the training can induce adaptations similar to those associated with more prolonged period of continuous moderateintensity exercise, which makes it relatively timeefficient.
The “cons” include the uncomfortable feeling of HIIT owing to the relatively intense effort that is required in order to make the training timeefficient, and also the potential greater risk of injury especially if running is performed as compared to less weightbearing activities such as cycling or swimming.
While HIIT is effective to improve fitness, there is no magic formula or “one size fits all” approach that is best for everyone, and indeed the best longterm approach is a varied strategy that incorporates strength, endurance and speed sessions as well as flexibility exercises and proper nutrition.
