Spine Leg Raise
This targets the lower abdomen, and is going tighten that pelvic region.
Make this effective by keeping your lower back flat on the floor.
Lift legs slowly upward and then let them down slowly, maintain control.
Inverted Toe Touch
This is an exercise made to blast those obliques.
Lie on your back and keep space between chin and chest.
Lead with your chest, straight legged all the while, alternate the toe touch .
V up
This is a fun one to do, kind of like a combination of the last two.
Lay on your back then lead with your chest while you contract at center.
This is going to move the tension to the center of the abdomen.
Burbees
This is my favorite because it works as a great full body exercise.
Do this for 15 minutes a day to burn calories and shrink that waistline.
Jump in the air, squat to the ground, hop into a pushup, then do it all in reverse.
Plank
This is probably the most effective way to strengthen and tighten the core.
Keep your back as straight as possible. Maintain hold till exhaustion.
Forearms to the ground back parallel to the floor.
Belly Blast
This really tightens and brings the stomach inward.
This one is undoubtedly the best.
In plank position do some funny little butt movements.
