Old school work-outs like star jumps, hopscotch and skipping may sound like nothing more than a good old laugh, but apparently they do a whole lotta good.
These timeless classics apparently burn more calories and use more muscles than our more usual exercises.
Experts claim skipping for 15 minutes can burn up to 215 calories, compared to the 150 calories burned from 15 minutes of running.
Similarly, those that enjoy a brisk walk would only lose an average of 50 calories in quarter of an hour, but could expect to shed 135 calories by doing star-jumps for 15 minutes.
A few fun minutes of hopscotch will see people burn around 88 calories, while a much more enjoyable game of It burns significantly more, 115 calories.
Even A-list celebrities are going back to their school days by using playground games to keep fit – with Beyonce and Michelle Obama hoola-hooping to stay slim, while Kate Hudson and Justin Bieber regularly skip.
Kate Toland, Head of Marketing at Fitness First says: "The question is, are you as fit as a six year old?
"While it might sound like child's play, this kind of exercise is not for the faint hearted. Functional training challenges your body in a new way every time, promising significant calorie burn – and its great fun!
"We applaud and encourage people to take any kind of exercise. But for those looking for the extra edge, we have brought this new school of thinking to life in our clubs which all boast giant playgrounds for adults called 'Freestyle' areas.
"Here you'll see members doing everything from skipping and interval training, to using trampolines and throwing balls."
