Every year a new fitness craze or diet fad comes along that promises to make you healthier and better looking, and that you'll have more friends and be cooler too. 

Zumba swept the globe and has seen a bit of a decline recently, the shake weight (that was fairly dodgy looking) and all sorts of strange fads have dominated the exercise world wherever there looks to be a quick buck to be had, but 2015 looks set to have a new exercise craze that...well it's not that new. 

The folks at the American College of Sports Medicine predicted most of those, and they poll fitness professionals every year to see what the next big thing coming down the track is bodyweight workouts. That's a fancy term for the old school workouts that you probably remember from your first classes in PE back in the day, and/or the first time you ever walked in to a gym.

Push ups, pull ups and their ilk narrowly beat out high intensity interval training (HIIT) and look set to be the craze this year because of the fact that they're inexpensive and hugely effective; there's a reason that they're still around after all these years. You can do them almost anywhere as they use only your own body weight (hence the name), and for overall strength and fitness, there are few moves that will do more for you than a pull up.

If you want to get a head start on the competition, then we've got a quick circuit that you can do to get a taster of what it's going to be like, and you can then turn to your friends and say you were doing this before it was cool. You're aiming to hit a total of 100 reps in as fast a time as possible, but concentrate on your form and make sure that you don't sacrifice that for the sake of speed. Once you've timed yourself once, aim to beat that time on your next outing. 

25 pull ups

25 push ups

25 squat jumps

25 burpees

You can do these in any format you like, for example two rounds of ten reps and a round of five, five rounds of five reps, or 25 each straight, it;s up to you. The only thing to keep in mind is to move from exercise to exercise (10 pull ups then 10 push ups, 10 squat jumps, 10 burpees and back to 10 pull ups and so on) with as little break as possible.
