Anyone with an interest in fitness will have heard of High-Intensity Interval Training, the darling of the fitness world right now and with good reason. HIIT involves short bursts of intense exercise followed by a planned recovery. Follow our plan with these five key exercises and you’ll see results, fast. If you then want to take it further, check out the best online personal trainer and fitness apps.

Aim to be out of breath at the end of each ‘set’ but ready to perform optimally again after each rest period.

What’s so great about HIIT?

It's very time-efficient: you can burn a lot of calories in a short amount of time. The average session can last between 20 and 30 minutes but can be much shorter depending on how hard you are able to push yourself whilst being sensible and safe.

Your metabolic rate is higher for hours after exercise, which means your body carries on burning calories.

Researchers have found that HIIT increases your metabolism more than jogging or weight training.

It can help you lose fat. The study found that people performing HIIT three times a week for 20 minutes lost an average of 4.4lbs of body fat in 12 weeks with no dietary changes.

It can improve muscle strength and increase your cardiovascular fitness.

HIIT workout exercises guide

1. Walk out

Start in a standing position with your knees slightly bent and feet shoulder width apart. Squat down lowering your hands to the floor, place your hands on the floor shoulder width apart then “walk” your hands outwards away from your body in a straight line to a plank position. Then walk them back in bending your knees and keeping your chest high, come back to standing position.

MODIFICATION: Keep your knees on the floor when walking the hands in and out.

2. Burpee

Start in a standing position, lower yourself to the floor placing your hands  flat just wider than your shoulders beside  your legs. Jump legs back in a straight line  to plank position, jump your feet back in bringing your knees to your chest, jump  upwards to an upright position.

MODIFICATION: Instead of jumping  the feet back, extend one leg back at a  time and remove the jump at the end.

3. Squat Jump

Place feet shoulder width apart ensuring your toes are facing the same direction as your knees. With your weight in your heels sit backwards as though you were sitting into a chair, then using your arms to propel, jump up. When  squatting check that your knees do not bend forwards over your toes.

MODIFICATION: Replace the jump with a calf raise by coming up onto your toes at the end of the squat and contracting your calf muscles.

Top tip: Focus on technique not speed, engaging the core muscles throughout

4. Press up

Place hands flat on the floor just wider than your shoulders. Take the feet back to achieve a straight line with the body. Lower the body to the floor by bending from the elbows then push up to return to the top position, keeping a slight bend in the elbow.

MODIFICATION: Keep your knees onthe floor to create a box position or take the knees further back to a ¾ press up.

5. Star jumps

Start in a standing position with your arms by your side and knees slightly bent, squat backwards then jump up extending your arms and legs into a star shape in the air. Land softly with your knees together and hands by your side.

MODIFICATION: Jumping jack – jump your feet out to the side landing on the floor and jump back in or walk your feet out and back in.
