Dr Bradley Elliott, Lecturer in Physiology in the Faculty of Science and Technology at the University of Westminster, appeared in ITV’s breakfast show Good Morning Britain to discuss common questions regarding the process of getting fit at the beginning of the year.

Dr Bradley Elliott noted that people can easily give up their resolutions to get fit, discouraged by the fact that they do not know where to start from.

High Intensity Interval Training (HIIT) was described to be growing popularity in gyms because of its brevity.

However, in order to test whether HIIT is the best way to get in shape, Bradley Elliott compared the energy that two men were burning, while cycling with different speed.

The experiment showed that 30 minutes of continuous exercise of low intensity burnt 200 calories, while the same exercise done with more intensive speed but in a time period of 90 seconds (HIIT), burnt 150 calories. Noting that both types of exercises are equally healthy and there is only a relatively small difference in the energy they burnt, Dr Bradley Elliott concluded that the intensity and timing are matters of personal preference.

Asked whether a morning workout is more beneficial than an evening one, Dr Elliott explained that exercising in the morning is better for those who have recently started to work out as they are expected to recover faster and enjoy a healthy sleep.

Dr Elliott also suggested that if a workout is not complemented by any other physical activity, it does not actually enhance lifestyle quality. Simple changes to lifestyle such as getting off the bus earlier or taking the stairs can contribute significantly to a fit and healthy body, he mentioned.

“What you can do is be a little bit more active but all of the time and be quite disciplined about it,” Dr Elliott added.
