Tighten your mid-section in by pulling your belly button down to the floor or by pressing the small of your back down o the floor so there is no gap between your back and the floor. You shouldn’t be able to slide your hand under your back while tightening.
Hold in the tightening phase for a count of 3-5 seconds, then relax, that equals 1 rep and repeat.
I perform this exercise 2-3 sets of 8-10reps
**IT IS HIGHLY SUGGESTED FOR MOTHERS JUST STARTING THESE PROGRESSION CORE EXERCIES TO USE A TOWEL TO APPROXIMATE THEIR ABDOMINAL WALL WHILE GOING THROUGH THE EXERCISES. AS IMPROVEMENT IS MADE/NOTICED, THATS WHEN THE TOWEL CAN START BEING WEANED OFF AND USING YOUR HAND FOR APPROXIMATION.
