Forget fancy gym equipment and tech – sometimes, there’s nothing like a simple bodyweight exercise to really get your body trembling.

If you get it right, the humble plank is guaranteed to get your core muscles shaking like a leaf. The best thing is, you can do a plank anywhere, any time, wearing almost anything.

Planks also feature in lots of other bodyweight exercises like push-ups, burpees and mountain climbers, so they really are worth nailing. When done correctly, you’ll work your abs, glutes, hamstrings and quads, biceps, triceps, and shoulders – it really is an all-in-one exercise.

The idea is to stay as still as possible for as long as possible. Outside, you’re an oasis of calm…it doesn’t matter what fresh hell is going on inside after a minute or so.
