People often wonder if flexing their abs actually builds muscle. In short, yes, flexing or contracting muscles does help strengthen the muscle fibers that are being worked, however, it’s important to note that this doesn’t build muscle mass as it only works the muscle isometrically (meaning without any movement). However, when done correctly, it can help strengthen your core and also activate a hard-to-reach layer of muscles known as transverse abdominis.
It’s also important to know that getting your abs to be visible requires a combination of diet, regular exercise, and low body fat percentage. No matter how many crunches you do, if a layer of fat covers your abs, they won’t be visible. This can be achieved by creating a calorie deficit through eating a healthy diet that includes lean proteins, fruits, vegetables, and whole grains. In addition, regular cardio workouts and targeted strength training exercises can help burn calories and reduce abdominal fat.
To flex your abs, lie on a flat bench with your back and shoulders straight, knees bent and feet on the floor, and arms raised in front of you, parallel to the floor. Contract your core and flex your abdomen, pulling your navel towards your spine. This should activate the muscles in your stomach and obliques, as well as helping to strengthen your core and improve your posture. Hold the contraction for a second and then release. Repeat 10 to 12 times, three to four times per week.
