How to train abs

1.1, Lifting Leg Curls

Lie on your back on the floor, with your lower back pressed against the ground. Put your hands on the side of your head and open your arms. Lift your legs up to 90 degrees from your upper body, cross your legs and bend your knees slightly. Exhale, contract your abdominal muscles, lift your upper body without lifting your lower back off the ground, hold for 2 seconds, and then slowly return to the starting position. Keep your chin slightly tucked in front of your chest.

1.2, reverse curls

Lying on the floor, lower back close to the ground, hands on both sides of the torso, legs lifted and upper body at 90 degrees, legs crossed, knee joints slightly bent. Tighten your abdominal muscles, then exhale and lift your hips slightly, lift your lower back slightly off the ground, hold for 2 seconds, then slowly return to the starting position.

1.3, traditional curls

Lie on your back on the floor with your lower back pressed against the ground. Place your hands on the side of your head and open your arms. Keep your legs flat on the floor and bend your knees. Keep your chin to your chest, contract your abdominal muscles, exhale and lift your upper body, keeping your lower back off the ground for 2 seconds, then slowly return to the starting position. The muscle growth cycle is 3 months for a cycle, so training at least three months. If you don't have a lot of belly fat, you'll see a lot of improvement in about three months.

Also, how long it takes to build abs depends on the individual. If you can stick to it, then almost a month after the results, more practice a few months the effect is better. If you can't stick to it, do it all the time off and on, so down will not have the effect of exercise.
