To gain some insight into how I keep fit, I'm sharing my favourite core workout. And the best thing about this? It only takes 15 minutes to complete!

Do each of these exercises for 45 seconds and take a 15 second break in between. You will do this sequence twice, then finish with a one minute plank.

Knee tucks
Start in a push up position.
Kick both feet in and bring your knees to your chest.
Keep your abs braced and your back strong throughout movement.
Kick both feet back out until your legs are almost straight. 

Mountain climbers
Place your hands on the floor directly under your shoulders.
One leg tucked, one leg extended.
Weight should be placed on the balls of your feet.
As quickly as possible 'climb' by alternating legs back and fourth to complete the target timeframe.

Repeat the circuit and finish with a one minute plank.

Plank
Start on your knees, put your forearms on the ground and ensure that your elbows are stacked under your shoulders, this will help with your stability.
Now straighten your legs so your body is being held up by your arms and feet. Engage your core, squeeze your glutes and hold for one minute.
