Bodyweight training requires no fancy, expensive equipment, just of course your own body weight.

A worldwide survey of fitness trends for 2015 has listed squats, lunges, push-ups, burpees and planks as the No 1 fitness trend for the coming year.

But just because no machines, dumbbells or weights are required does not mean it’s easy. These movements are some of the most efficient ways to get in shape and strengthen muscles – so they are certainly intense.

Bodyweight training is quite a general term but it’s effective. Burpees, for instance, are exhausting.

Better still, this sort of training can be done practically anywhere from the living room to the park.
