The long arm crunch is ranked the 6th most effective ab exercise, changing the traditional floor crunch by straightening the arms behind you. This adds a longer lever to the move, adding a bit more challenge and difficulty. This move also emphasizes the upper part of the abs, although it's important to remember that your rectus abdominis is actually one long muscle that travels from your lower chest to your pelvis. While you can emphasize one part, any exercise you do will work the entire muscle.
Lay flat on your back again for this one but this time, place a dumbbell between your feet with your knees completely bent and thighs pointing straight up. Hold on to the dumbbell with your feet and bring your legs up toward your chest making sure your lower back gets off the ground. Focus on using your abs to pull your legs up and not getting momentum from your knees or feet.
The first step to finding your six pack is to clean up your diet. If you want to see your ab muscles, you need to decrease your overall body fat. Get rid of processed "junk" foods, sugars and processed carbs. Eat more vegetables, nuts, and fruits, organic lean protein and healthy fats, such as olive oil, fish oils, and avocados. Try eating several small meals each day and avoid late night snacking. Eat some protein for breakfast, lots of vegetables, fruits, and fiber and drink water rather than calorie-laden beverages. Don't cut calories drastically or you could inadvertently lower your metabolism. Bottom line: eat more high quality, nutrient-rich foods and eat fewer empty, processed calories.
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.)
The crunch is the most popular abs exercise because anyone can do it. But that doesn't mean it's the best exercise for training your middle. "Crunches flex your trunk," says David Jack, owner of ActivPrayer in Phoenix, Arizona and creator of Men's Health MA40 Workout. "But the main function of your core is to prevent movement and resist force through your torso."
No matter how strong your core is, you aren’t going to see a six-pack if your muscles are hiding behind a big layer of fat, says Jim White, R.D., owner of Jim White Fitness & Nutrition Studios in Virginia. “Each individual is going to be slightly different, but the ideal range of body fat in men is eight to 20 percent,” he says. Get below six percent and you could compromise your health.
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.
BMI vs Body Fat Percentage- Body Mass Index or BMI calculates your ideal weight in relation to your height. This isn’t a great way of determining whether someone is healthy because it completely ignores how much muscle an individual holds. A better alternative is determining your Body Fat Percentage -BFP and then take a cue from your BMI as to how healthy you are. Here’s a visual comparison of how different body fat percentages look like. You can get your BFP measured by a Bio-electrical Impedance Scale found at gyms or at a nutritionist’s clinic.
The optimal caloric deficit when you are training 4 times a week is different than the optimal caloric deficit for merely losing weight. You must eat enough food to fuel your training and feed your muscles but still be in a state of a caloric deficit to keep burning fat.
