Top 10 Proven Ab Killers of All Time

2. Abdominal Holds

While abdominal holds look like a rather easy ab exercise, they are anything but.

This hard-core exercise works both the deep transverse abdominus muscle and the shallower rectus abdominus, which is the group that gives you the six-pack look.

One great thing about the abdominal hold is that you can do it whenever you find yourself sitting in a chair.

You can sneak in a few at work or perform them during commercials while you’re watching TV.

Make sure you’ve got a sturdy chair (no wheels, please!) and move slowly and deliberately to avoid injury. Sitting on the edge of a regular chair with your hands next to your hips, gripping the edge with your fingers pointing toward your knees.

Keeping your back straight, tighten your abs, pull your feet a few inches off the floor and lift up your buttocks. Hold this position for as long as possible, then gently lower yourself back down, rest a moment and repeat. Aim for a full minute of this ab-killing exercise several times a week.

Once you’ve mastered the traditional abdominal hold, try starting with your feet together in front of the right leg of the chair.

Lift yourself up and slowly sweep your feet in a high arc from the right leg of the chair to the left leg, keeping your back straight and your abs engaged. Repeat the arc back to the right side, repeating ten times.
