Description
Yi Li and Xi Chen present a 2026 study of exercise, mental resources, and body image in Chinese university students. They survey hundreds of students twice, three months apart. Mental resources, called psychological capital, cover hope, confidence, and bounce back strength.
More exercise at the first survey predicted stronger mental resources and better body appreciation later. Mental resources also predicted later body image, and carried about a quarter of the exercise effect. Not all exercise doses behaved alike. Time per session showed a curved pattern, while intensity rose in a straight line. The title's warning holds: for body image, more is not always better.
