Tighten Your Core With Sit Ups

Step One: Lie on your back on the floor, bend your legs and straighten your arms in front of you or place them at the back of your head.
Step Two: Lift your shoulders off the ground by engaging your core, then raise your upper body off the ground until it seems as if you’re sitting up straight
Step Three: Lower your body back to the ground.
Step Four: Complete 15 reps and do a least 3 sets.
