Before you start doing a core workout routine, you need to figure out exactly where you are on the core-strength scale. That’s what the Plank Test is for.  The Plank Test will check your core strength with one simple exercise. Lay on the floor face-down, place your elbows directly below your shoulders, draw in your belly, and raise yourself off the floor. Clench your butt cheeks and keep breathing normally. Your feet should be in a vertical position, your toes touching the floor/exercise mat. Your body should be completely straight, like a plank of wood. The moment you’re in this position, count how long you can hold it.  If you’re able to hold this position for 30 seconds or less, you are considered a beginner. If you can do between 30 to 60 seconds, you are at the intermediate level. If you can do more than 60 seconds, you’re at an advanced level.  If you’re a newbie, it’s best to focus on getting the right form and the basics down pat.  This is why I always recommend beginners to master the draw-in, which is the starting position for many core exercises.  For this position, you need to lie down on your exercise mat, put both legs up, bend your knees, and place your feet flat on the floor. Tighten your ab muscles while tucking in your tailbone. Think about how you’d act if you were going to be punched in your stomach.  Remember, no matter what fitness routine you have, strengthening your core should be a regular part of that.
