Interval training is often considered beneficial only for endurance athletes at a high level of performance and thought of as only being beneficial for members of this rather small group.

During the past 10-15 years scientific studies have shown, time and time again, that just about everyone can benefit from interval training, provided we keep up a good enough form (for injury prevention) and high enough intencity (to maximize the outcome).
Different studies have repeatedly shown that the use of HIIT can increase both the unaerobe (work under oxygen deficiency that leads to accumulation of lactic acid) and aerobe (lower intensity work with enough oxygen supplied by the blood stream) capacity while lower intensity steady state cardio only increases the aerobe capacity.
In addition we create a so called EPOC (Excess Postexercise Oxygen Consumption), increasing our metabolic rate over a period of up to 72 hours after completion of the workout, that means a higher rate of fat burning while we are recovering from our workout - isn´t that neat?

On top of that the use of HIIT can save us a lot of time if we choose different full body strength training exercises and combine them during our interval training. Hereby getting our cardio and strength conditioning done and at the same time creating improvement in balance, posture and functional stability by the nature of exercises choosen for the job.

So, what´s the downside?

Well, it´s tough, sometimes even really, really tough.........

Finally I´ve never before come across a workout model as fun, challenging and rewarding that leaves me experiencing such a exquisite feeling of exhaustion in the body as HIIT based on functional strength and full body engagement!
