How to do the perfect plank
-
Begin by kneeling on all fours with your hands shoulder width apart.
-
Next kick your legs back so that your body is straight – get onto your toes, with heels off the floor.
-
Bend your elbows to a 90 degree angle so that you are resting on your forearms. Your forearms should be directly below your shoulders, this should result in your body forming a horizontal line
-
Ensure that no other part of your body touches the floor, maintaining the horizontal line position and refraining from sticking your behind in the air.
-
Hold the position for the time outlined on each day of the challenge.
