We all know what it's like to want to work out but not have enough time to set aside a full half-hour/hour to exercise. That's why sprint interval training is perfect – all the benefits of a full workout, in a fraction of the time. Reebok trainer, Claire Burton, joined the ELLE Running Club and showed us how it's done.

We started off with the all-important warm up by jogging to a nearby park, where we stretched to loosen connective tissues and lubricate our joints, which is very important to do before increasing your core body temperature. Claire then marked out a distance for the sprint – based, approximately, on a 50 metre square area of grass in the park – using an equal distance for a jog recovery. Each circuit comprised of two sprint intervals and two recovery jogs.

We repeated this four times. Yes, that makes eight sprint intervals. But what a workout. Followed by a gentle jog back to recover.

There are many variations to sprint interval training, so you can always find new ways to challenge yourself and your body. Plus, your metabolism is elevated for several hours afterwards, so just think about all the guilt-free food you can eat once you're done…
