What is the Rationale of an Exercise Timer on HIIT?
High intensity interval training relies on accuracy of timing. Work too long and you exhaust yourself before you finish all your round. Work too slowly and you do not get cardiovascular benefit because your heart rate is at the training zone or lower. The exercise timer eliminates this mental load completely, instead allowing you to focus on the form, breathing, and effort instead of worrying about the clock every now and then.
It is a free online exercise timer which will automatically switch between work and rest periods and which will announce each change with specific audio feedback and display your current round in real time. The oversized countdown clock can be seen just by looking at it even in the hardest workout when sweat and work blur your eyes.
The Science Behind HIIT
HIIT involves alternation of anaerobic work segments, i.e. periods when you make efforts to reach the verge of your maximal capacity, and short recovery periods in between when your cardiovascular system is partially restored before the next round. This produces a great metabolic effect known as excess post-exercise oxygen consumption (EPOC): your metabolism is still high hours post-training, and consumes extra calories at rest.
Between exercises in a workout, to have a time interval between them, use our Countdown Clock Timer. The 30 Minute Timer is effective to time entire blocks of the workout in the case of normal sessions.
