1. Observe the original picture and decide where to add abdominal muscles. Use the rectangle tool to draw a rectangle directly, pay attention to choose the shape instead of the path, don't choose the stroke color, and then adjust it at the corner to make the right angle become a rounded corner, which becomes more natural.

2. Copy the shape to form three groups of abdominal muscles. CTRL+SHIFT+ALT adjusts the size of the upper and lower parts, which can form a top-down feeling. When finished, combine all the shapes into one layer.

3. Filter Gaussian blur, and then copy the layer to make the effect of Gaussian blur more prominent.

4. Double-click to enter the layer style, adjust various parameters of the bevel relief, pay attention to the data adjustment of the arrow, and then adjust the opacity to make the abdominal muscles become a piece of the body. Adjust the data again, so it is realistic.

abdominal muscle

Abdominal muscles are an important part of human connective tissue, including rectus abdominis, oblique abdominis, oblique abdominis and transverse abdominis. When they shrink, they can bend and rotate the trunk. Abdominal muscles also play an important role in the activity and stability of lumbar spine, and can also control the activity of pelvis and spine.

Viscera exists in the abdomen, and the whole abdominal muscle surrounds the viscera in a ring, thus playing a better protective role. Abdominal muscles also play a role in keeping the trunk straight and the body stable. If your abdominal muscles are too weak, you may not be able to stand up. Your body is always in a state of trembling, so you can't keep stable.
