CORE – Plank
The core-engaging plank is an oldie, but a goodie. The longer you can hold it, the stronger you are getting.
1. Make sure your elbows are directly below your shoulders, your hands are pointing forwards and you have a 90 degree bend in your elbows. Ensure your body is fully extended and you are balancing on your toes. Don’t let your butt go too high in the air and make sure you have one straight line from your shoulders, bum and heels. The last thing to do is clench your bum and your abs and try to pull your belly button up to your spine. Hold this position.
