They are flat.
The abdominal muscles play three main roles: stabilizing the body, keeping the trunk solid when external forces act on it, and controlling forward flexion and rotation movements. The rectus abdominis, the muscle responsible for that six-pack look, is divided into two sections by connective tissue. As such, the lines that run vertically through it and those between them can vary between individuals depending on where they are located on our body.
They are sculpted
While achieving well-defined abs takes effort and dedication, they are a great indicator of overall health. To achieve that chiseled look, combine strength training, cardiovascular exercise and a nutritious diet. To achieve an ideal abdominal shape, it is important to burn excess body fat. A reliable guideline is to reduce your calorie intake by 500 calories per day, according to the American Council on Exercise.To maximize fat burning, the ideal method is high-intensity interval training (HIIT). This type of training raises your heart rate into the stratosphere and encourages fat burning. Other options include plyometric exercises like jumping jacks and squat jumps, as well as cardio workouts that raise your pulse to at least 85 percent of your maximum heart rate.
They are rounded
When it comes to getting that desired flat stomach, everyone is different. Genetics play a role, but the most effective way to get defined abdominal muscles is through proper nutrition and regular exercise - it's no secret that having an attractive midriff is one of the greatest rewards for any fitness enthusiast.
They are torn.
Train hard and stay disciplined to achieve your abs, but also incorporate a healthy diet into the mix. Reduce your added sugar intake and increase your lean protein intake for optimal results. By doing this, you will help reduce body fat by having less subcutaneous fat (the kind that can be seen from the outside) and more visceral fat (found inside the abdomen). This is what gives your abs their chiseled look.
