Pay attention to the ratio of shoulder strap thickness and back buckle width to be no less than 0.5 inches to 2 inches.

The bust must be supported by steel rings to reduce the burden on the shoulders. The breast point should be at the fifth rib to avoid sagging of the chest.

The back strap should be held evenly under the shoulder blades.

When viewed from the front of the shoulders, the chest line is in a horizontal line. When viewed from the side, the central axis of the shoulders is straight and does not lean forward or backward.

The shoulder straps are placed evenly on the top of both shoulders, not too tight or too loose, and can accommodate one finger.

After putting on the bra, the body can straighten naturally.

Equipped with a titanium metal soft rod design, it supports the lumbar muscles evenly, achieves a force-relieving effect and protects the lumbar muscles, and reduces scoliosis caused by muscle imbalance.

The material must be supportive, reduce the pressure of the lumbar spine tilting forward or pressing down, maintain the normal physiological curvature of the lumbar spine, and reduce spinal problems caused by lumbar spine misalignment.

The stomach and abdomen become flat from the front, and the lumbar spine from the side no longer tilts forward.

The pelvic and hip muscles are completely surrounded, reducing the imbalance of gluteal muscle strength that may cause spinal problems in the lumbar and sacral vertebrae.

The trousers must completely surround the thigh muscles to protect the quadriceps and popliteus muscles (gluteus maximus) to avoid muscle sprains.
