Choose a smooth, clear floor. Tiles or a wooden floor would work well, and ensure you have enough space to stretch out.
Fold a small towel, big enough to place your feet on, and one that will easily slide across the floor.
- Get into the plank position, with your feet on the towel and elbows on the floor. You may want to use a non-slide mat or rug below them for comfort. Keep your shoulders in line with your elbows and your back as flat as possible, while pulling your tummy button in towards your spine to properly engage your core.
Continue to engage your core and pull your legs into the pike position, so that your body looks like an inverted V. Keep your core and abdominal muscles working, and straighten your legs as much as possible without locking your knees.
- Return to the plank position and repeat this exercise for 30 to 60 seconds or more, depending on your level of fitness. Aim to do it up to 3-4 times a week for a noticeably strengthened core and abs.
