HIIT workouts can last between four and 30 minutes

Pros and benefits of HIIT

It's time efficient

As HIIT sessions are so short they're perfect for anyone with a busy schedule. Whilst you may not have time to make your way to the gym, everyone has a spare few minutes that they can dedicate to working out.

You burn more fat

As the body is being exerted fully its repair cycle ramps up to match this, meaning you can burn more fat in a shorter space of time.

It can be done anywhere

Although you can incorporate weights and machinery into your workout, no equipment is required, so you can easily exercise at home. Doing exercises like push-ups, burpees and lunges means you're only working against your own body weight.

It can increase your metabolism

Research has shown that the stimulation of the human growth hormone can rise by up to 450 per cent after a HIIT workout, which in turn speeds up your metabolism.

Cons of HIIT

It's not suitable for everyone

As HIIT training is so intense you must already have a basic level of fitness to take part. If you're not used to exercising the workout could cause undue stress on your heart.

It can cause dizziness

If you're alternating between standing and sitting at speed your blood pressure can drop quickly, making you feel dizzy. If this happens you should take a break until you feel ready to continue.

It can leave your muscles feeling sore

Whilst the exercises are only brief, because you're working at such a high intensity you can end up overexerting yourself and can run the risk of damaging your muscles.

There's a higher risk of injury

As you're moving at such a fast speed your form may not be correct on some of the exercises, so make sure you know how to position yourself. If in doubt, ask a personal trainer or a member of gym staff for advice.
