How do you do the plank exercise?

The plank is used for inner core strength, this helps things such as balance.

Firstly, lay face down on the floor, place the tips of your toes on the floor too.

Next, rest the weight of your upper body on your elbows and forearms, trying to keep your back straight. Lift your body off of the floor so only your elbows, forearms and toes are tocuhing the floor. Now hold this position for 30 seconds and rest.

Repeat and slowly increase the time you perform it for. If done correctly on the 2nd-3rd attempt your body will start shaking, don't worry that's a good thing.

Hope this has helped. =)
