Why it made the list: This harder version of the Russian twist works the obliques while requiring the upper abs to contract isometrically. To recruit the obliques, you either need lateral flexion (bending to your side), trunk rotation (twisting), or sucking in your belly. Doing your twists works the trunk-rotation function of the muscle, so really focus on the contraction. Try to get a little crunch on either side after the rotation to up the ante.
1. Consume fewer calories than you're burning every day. Job one when trying to achieve a six-pack is to lose weight, which means expending more calories than you take in on a daily basis, says Dani Singer, a certified fitness nutrition specialist and certified personal trainer in Baltimore. He's the director of Fit2Go Personal Training. To optimize losing fat and not muscle, you need to be in a caloric deficit, eat adequate protein and strength train, he says. "The source of your food will affect health, but will have zero effect on your body composition," Singer says. "It's the total calories and macronutrients [protein, fat and carbs] from your foods that will determine how your body looks."
Muscles exert higher EMG tension when they are contracting eccentrically (lowering the resistance) versus raising it; but the problem with most exercises is that the amount of weight you can lower is limited by how much you can lift positively (concentric work). This exercise compensates for the problem by changing the leverage during the lowering (eccentric) phase of the exercise.
Ah the six-pack. The goal of most every fitness enthusiast. A tight, lean, shredded stomach not only looks great, but also feels great and builds more confidence. Let's face it, a chiseled midsection is something we all strive to strut. Unfortunately, not everyone is willing to put in the time and effort to build this work of art. For those that do however, the rewards are well worth the struggle.
To do it: Lie on your back with your hands interlaced behind head, knees bent ,and feet hip-width apart on the floor. Inhale and lift your chest towards your knees, bringing your shoulders and head off the floor, maintaining a neutral pelvis (keeping it parallel to the floor). Exhale and rotate to the right side, and then exhale again rotating even further, lifting a little higher. Next, inhale and lift as you return to the center and repeat to the other side. Do 8-10 reps per side.
To do it: Stand with your feet hip-width apart. Bend your knees slightly (or more if needed) and place both hands flat on the ground. Keeping your legs extended and your feet planted, walk your hands away from your body, as far past your shoulders as you can, until you are in a full plank position. Hold for one count at the furthest point, and then walk your hands back to your feet and slowly return to standing. That’s one rep. Repeat up to 10 times.
Most core exercises hit a certain part of your core: your rectus, your obliques, and so on. But the high-cable split stability chop is the one exercise that hit your entire midsection. Yes, it’s not as strenuous on each individual fiber as some other moves. But it will hit more spots than anything else, which is why it’s a great exercise to slate in to your routine. Here’s exactly how to pull it off.
So let's get to it. Here are the experts' choices on the most effective abdominal exercises. These should be performed two to three times weekly (for beginners, two is plenty to start). Each exercise should be executed until the point of momentary muscular failure, which should happen between 30 and 90 seconds. This is considered one set, which should be no more than 15 to 20 repetitions. Rest for 30 to 60 seconds. Concentrate on performing each exercise slowly with good form. Work up to completing two to three sets of each exercise.
But instead of just trying to perform as many reps as possible, slow down and really focus on the quality of the movement—especially the eccentric, or downward motion, of the exercise, he says. “The eccentric contraction is the most important phase when sculpting any muscle.” Plus, focusing on quality over quantity will help protect your back (some experts say crunches can be potentially troublesome for guys with back issues.)
