The majority of us will know that we should be exercising as part of a healthy lifestyle, but many are put off because they don't have the time. The current recommendation is 150 minutes of moderate-intensity physical activity, or 75 minutes of vigorous-intensity exercise each week. 31.1% of the adult worldwide population fail to meet these minimum recommendations, and this is often as a result of a lack of time, low motivation and poor exercise adherence.
HIIT involves alternating short bursts of anaerobic exercises for 6 seconds to 4 minutes with lower intensity activity for recovery. Scientific studies have indicated a 12-week programme of HIIT, performed three-times a week, improves VO² max and insulin sensitivity, and reduces blood pressure. This form of training not only boasts health benefits, but is also a huge time-saver to those who struggle to fit exercise into their daily routine. You will have to work hard though, reaching 85% of your VO² max will leave you out of breath and sweating, but you'll feel great afterwards!
