What are the Best Ab Exercises?
Recent studies in California looked at thirteen common ab exercises and ranked them with regard to effectiveness based on muscle stimulation (measured by an electromyogram (EMG) which measures the electrical impulses of muscles at rest and during contraction) in the Rectus Abdominis and the Internal and External Obliques. The more activity the higher the ranking assigned.
The results showed that the most effective abdominal exercises were the ones that required constant abdominal stabilization, as well as body rotation. The top 3 ab exercises were:Â Bicycles, The Captain’s Chair, and Crunches on an Exercise Ball, in that order.Â
Bicycles and the Captain’s Chair are more advanced exercises and should not be attempted by beginners. As beginners have yet to develop adequate strength of the torso and the neck to handle these advanced exercises and could injure themselves.
One surprising result was that the traditional crunch ranked 11th out of 13. The study also showed slight differences in which exercises would give you the most effective workout for the rectus abdominis or the obliques. Bicycles and the Captain’s Chair were no 1 and no 2 on both lists, with Bicycles the best for the rectus abs, and the Captain’s Chair the best for the obliques.

Here is a brief outline of how to do each exercise.
Â
Bicycle Crunches
Lie flat on your back, lower back pressed into the floor, thighs perpendicular to your torso, lower legs parallel to the floor, fingertips placed lightly behind your ears.

 Extend your right leg out at an approximately 40 degree angle from the floor, while simultaneously bringing your left knee in. Use your abs to twist your right shoulder and elbow up and across your body toward your left knee. Touch your knee with your elbow if you can. Reach only as far as you can without straining. Lower yourself back to the floor, then reverse the movement for the other side. Use a continuous fluid motion.
Â
Captain’s Chair
Rest your elbows on the support pads. Stabilize your upper body by lightly grasping the handles, lower back pressed against the back pad. Your hips and knees flexed at 90 degrees. Keep your head up, eyes looking straight ahead.
Using your lower abs, slowly roll your knees up toward your chest, curling your pelvis toward your rib cage. Your lower back should lift off the pad at the top of the movement. Pause at the top, then slowly lower back to the starting position. Don’t let your legs hang straight down. Don’t let them go past 90 degrees.
Â
Crunches on an Exercise Ball
Lie back over the ball with your back slightly curved over the ball. Your feet should be flat on the floor, shoulder width apart, with your thighs and torso parallel with the floor. Hands behind your head, with your fingertips lightly by your ears.
Contract your abs to lift your upper torso, lifting your shoulders off the ball. Don’t raise further than 45 degrees. Pause at the top, then slowly return to the starting position and repeat.
Â
Vertical Leg Crunch
Lie on your back (lower back pressed into the floor) with your legs raised straight up, knees over your hips, with knees slightly bent. Place your hands behind your head, fingertips lightly behind your ears.
Using your upper abs, raise your shoulder blades off the floor, rib cage rolling toward your hips. Pause at the top, then slowly lower back to the starting position. Lightly touch your shoulder blades on the floor and repeat. Don’t rest at the bottom.
Â
Ab Roller
Preparation: Kneel on the floor facing the Ab roller, thighs perpendicular to the floor and grip the handles in each hand.
Slowly glide forward to a stretched out position. Inhale as you’re moving forward. Keep your abs braced (as though someone was going to punch you in the stomach) throughout the movement. Using your arms and upper body, roll yourself back, exhaling as you return to the starting position.Â
                                                                              Â
 Reverse Crunches
Lie on your back with your lower back pressed into the floor. Head and neck should be relaxed, with your hands down at your side, palms down. Both your hips and knees should be bent at a 90 degree angle.
Contract your lower abs to raise your hips towards your rib cage, slowly curling your tailbone up off the floor. Your legs will reach towards the ceiling with each rep. Exhale on the lift, inhale and slowly lower your hips back to the starting position. Don’t push with your hands.
Â
The Plank
Lie face down with your weight on your forearms and toes. Elbows should be bent at 90 degrees and directly under your shoulders. Rest on your forearms, knees, and toes before starting
Lift up off your knees so that you are supported on your forearms and toes. Your back should be level. Keep your head in line with your body and spine in a neutral alignment, bracing your abs throughout the holding of position. Hold the planked position for 20 to 30 seconds to start with.
