Ab crunch 1
Laying on your back on a yoga mat, keep your core engaged with knees bent flat on the ground. Put your hands behind your head and lift as you contract your abs, but avoid pulling on your neck. Do 3 sets of 25.
Stir the Pot 2
This workout might look like it's easy, but it will target your core like you never expected. With a stability ball, place your forearms on top of it and place yourself in a plank position. Keep your knees above the ground and move your arms clockwise as if you were stirring a pot. Do three sets of 15 clockwise and another three sets of 15, counterclockwise.
Side plank 3
The side plank is the perfect workout to tone and strengthen your obliques and challenges your core. On a mat position yourself on one side with your forearm aligned with your shoulder. Make sure your legs are fully extended and you are strong and steady and lift your body up. Hold for 30 seconds of 3 sets on each side.
Flutter kicks 5
As you're laying down on a mat, lean back 40 degrees and lift your legs up several inches off the ground. Keep your legs straight and then alternate lifting your legs up and down as quickly as possible and then do them slowly. Go for 3 sets of 20 flutter kicks.
