Wearable technology has made it so much simpler to track vital statistics like our steps, calories as well as even sleep. A heart rate monitor, which comes standard with this type of technology, allows you to assess your fitness and spot any irregularities that your doctor should be aware of.

Why do you need to monitor your heart rate?

Your heart rate is a good signal of the amount of effort that you’re putting into a workout. Focusing on various heart rate zones permits you to concentrate on burning fat or increasing your stamina. By monitoring your heart rate, it is possible for you to avoid falling into the training traps of over- and under-exerting. This means that if you perform the correct amount of exertion you’ll be well on your way to achieving your fitness goals. Maintaining a good watch on your heart rate should, therefore, form part of any exercise regime which is why monitoring your heart rate is always a good idea every time that you do any form of exercise.

Endurance athletes accurately rely on their training pulse as a measurement of their fitness levels. Workouts at varying intensities are vital to progress in this area. Interval training, which refers to short periods of moderate effort in the aerobic zone which alternate with short periods above the anaerobic threshold, is a great way to become faster as well as develop stamina. The same is true for muscular-endurance training techniques such as HIIT.

What is HIIT?

HIIT’ – which stands for ‘High-Intensity Interval Training’ – refers to short, extreme, unsustainable surges of physical activity that are paired with periods of quick rests.  This kind of intense training causes a type of metabolic disturbance which can cause the body to burn calories at an increased rate up to 48-72 hours after your workout session.

HIIT training can also boost metabolism, lower insulin resistance, enhance cardiac function, cause faster gains in endurance levels as opposed to steady-state cardio training. Also, HIIT can be an effective way to recruit or build type 2 fast-twitch muscle fibres.  Slow-twitch muscles assist with enabling long-endurance feats such as distance running, while fast-twitch muscles fatigue quicker but are used in intense bursts of movements such as sprinting.
