Target Muscles: Rectus abdominis and obliques.

How to do it:
Start lying flat on your back, legs fully extended, and both hands behind the head. Begin by pressing your lower back into the ground. This will eliminate any arch in the low back and help engage your core before starting any movement. From here, bring both hands behind the head and raise the shoulders off the floor. Next bring your right knee toward your chest and simultaneously rotate your shoulders to bring the left elbow to toward the right knee. Make sure to keep the leg that isn’t bending fully extended and low to the floor to get the best engagement. After touching the right knee to the left elbow, rotate your shoulder and bring the left knee to the right elbow. Perform these movements slowly and controlled for the best core-burning results.
