A flatter stomach is one of the most common fitness goals, so it’s no surprise that there are more abdominal exercises and contraptions for achieving a tighter stomach than there are excuses to skip your workout. But not all ab exercises are created equal. In fact, many are simply a waste of workout time. A studyconducted at the San Diego State University Biomechanics Lab examined the electromyography (EMG) activity results garnered by popular core exercises. Here’s how they stacked up:
Don’t waste your time with:
1. The basic crunch Why: The basic crunch is just that – basic. Don’t waste countless hours on a less-than-stellar exercise that does little to fully engage your abdominal muscles and core.
2. The ab rocker Why: The ab rocker was proven to be no more effective than the traditional crunch. Actually, it was shown to be up to 80 percent less effective! Yes, it’s super easy to do, and that’s why it doesn’t work. By supporting your head, this tool actually deactivates the muscles in the neck that would normally support it. This can lead to neck pain as your supporting muscles weaken. There’s a reason these machines are collecting dust in the corner of your gym.
3. The straight-leg sit-up Why: This old-school exercise is responsible for many back issues. It puts a huge strain on the lower back by provoking you to hurl your upper body forward in an attempt to touch your toes. No thanks.
4. The standing dumbbell side bend Why: Isolating the obliques in this way is not natural and can add unnecessary strain to your back. (How often do you bend straight to the side to pick something up?) Also, many people use the momentum that the dumbbells create and rock side-to-side instead of properly engaging their muscles. Avoid these unless you want to look you’re rocking to the oldies.
5. The seated twist Why: Seatedtwisting machines are a waste of money and space in fitness facilities. They don’t train your muscles in a functional way and the path of motion is fixed and unnatural. They can also lead to injury if you don’t know what weight to use and how to control the movement. I’ve seen many people snap from right to left with some wicked momentum – ouch!
Opt for these five exercises to maximize your workout time instead:
1. The plank Why: It stimulates more abdominal activity than a regular crunch and works the muscles in your back as well. How: Supporting yourself on your forearms and the balls of your feet, bridge up and position your body in one straight line. Pull your abs in tight and hold for 30-60 seconds. Kick it up a notch: From the plank position, reach forward with your right hand, hold for a count and slowly return to the starting position. Do the same with your left hand and repeat.
2. The bicycle crunch Why: In the San Diego study, this exercise was the second highest in terms of EMG activity in participants. It also stimulates more abdominal activity than the traditional crunch including your lower stomach and obliques. How: Lying on your back, bring your knees up to form a 90 degree angle and keep your hands by your temples. Crunch up and twist across the body while simultaneously performing a bicycle motion with your legs. For example, if you crunch up and to the right you should draw your right knee in and vice versa. Repeat for 20-30 reps total.
3. Side plank Why: Side planks not only torch your obliques, they also stimulate and tone your glutes, quads, hamstrings, inner/outer thighs and your upper body. How: Lie on your side with your forearm perpendicular to your body and one foot stacked over the other. Bridge your hip up and hold for 30-60 seconds while maintaining a straight line with your body. Kick it up a notch: Raise your top leg so that it’s parallel to the ground (this full version of this is called Vasisthasana in yoga).
4. Vertical chair knee raise Why: It stimulated 210 percent more abdominal activity in the study’s participants than the traditional crunch. How: Use your upper body to hold yourself up tall while drawing your knees up and past your waist. Squeeze at the top and slowly lower your legs back down. Repeat for a total of 12-15 reps. Kick it up a notch: Do a straight-leg raise.
5. Reverse crunch Why: Engage your lower abdomen and obliques with this move. How: Lie on your back with your hands tucked under your bum and your knees bent. Bring your legs up until they form a 90 degree angle from your torso. Do a pelvic tilt and pull your knees in towards your chest, squeeze and slowly lower to starting position. Aim for 15-20 reps. Kick it up a notch: Hold a weight over your head.
Ripped abs plan:One of the best ways to work the abs is to perform a series of core moves in one continuous circuit. Circuits are efficient and effective, allowing you to get the most out of your efforts. For optimum results, perform this core circuit at the end of your intense training sessions. You want your core strong and ready to back you up when you’re in the thick of a tough workout.
Plank tri-set (regular and sides): 30-60 seconds Reverse crunch: 15-20 reps Bicycle crunch: 10-15 reps per side Vertical chair knee raise: 12-15 reps Notes: Perform 2-4 total sets or circuits with now rest between exercises and a 1 minute rest between circuits.
Tone up faster and target key muscles you never knew you had, with a handy weighted ball.
As shown on the Chatelaine magazine website.
1. Squat and squeeze
Stand with hands on hips, ball between thighs. Squeeze ball as you lower into a squat, until thighs are parallel to floor, li fting arms to shoulder height. Hold for five counts. Return to standing. Do 10 to 12 reps.
Perfect your form: Avoid bending knees beyond toes. Dial it down: Keep hands on hips. Amp it up: Increase reps and try squatting even lower.
2. Toning ball slam
Stand with feet slightly wider than hip-width apart, holding ball overhead. Engage your core as you drive arms down to slam ball onto floor in front of you, bending knees as you follow through. Quickly squat, using legs (not bending your back!), to pick up ball. Do 10 to 12 reps.
Perfect your form: Avoid locking elbows. Dial it down: Do fewer reps. Amp it up: Increase reps.
3. Side kick
Hold ball in your hands at chest. Shift weight onto one leg as you draw opposite knee into chest. Kick leg out to side, then immediately draw knee back into chest. Briefly touch foot to floor before kicking again. Do 10 to 12 reps. Switch sides.
Perfect your form: Keep abs engaged for balance. Dial it down: Ditch the ball. Amp it up: Increase reps.
4. Pullover crunches
Lie on back with knees bent, feet flat on floor. Hold ball behind your head, arms outstretched, keeping a good bend at elbows. Swing arms forward and engage abs to come up into a crunch, bringing ball toward legs. Do 10 to 12 reps.
Perfect your form: Engage chest and abs and avoid li fting from neck. Dial it down: Ditch the ball. Amp it up: Increase reps.
