“The energy shortfall and oxygen deficit that a sprint creates might potentially backfire,” he explains. “First and foremost, you’re not using fat as your major fuel source… the lower the intensity of the exercise, the more fat you’re using as your main fuel source.”

He next walks through his typical cardio workout, which consists of five 30-minute walking sessions.

If he discovers that he isn’t losing weight with this programme, he increases the intensity of his workouts by raising the inclination and speed on the treadmill while still walking for 30 minutes at a time.

And, in order to guarantee that he never misses a session, Revelia has placed his treadmill directly in front of the TV, so that this time may also be used for amusement. “Make your cardiovascular workout, your everyday regimen, pleasurable,” he advises. “If it doesn’t thrill you or give you joy, you’re considerably less inclined to do it.”

Diet is, of course, just as vital as exercise, especially if you want to lose weight. “You can’t just do exercise and expect to lose weight if you don’t pay attention to your nutrition,” Revelia explains. “Some sorts of cardio will actually increase your hunger… if you perform certain types of cardio, you’ll end up eating more to compensate for that energy,” he explains.

“You must have a baseline understanding of your daily calorie intake and everyday exercise,” he says. “You burn calories all day long, not just while you’re performing cardio… I’m not a huge fan of significantly reducing calories to lose weight because it’s only effective in the short term.

You’ll shed pounds at first, but ultimately you won’t be able to keep up with the low-calorie strategy, your body will adapt, you’ll start curtailing your movement patterns, energy efficiency will occur, so I’d rather we adopt the approach where we comprehend the harmony between how many calories we’re taking in and the movement we’re doing.”
