"运动可以让人感到快乐，增强自信心"用英语怎么说呢？

sports bring you happiness and confidence.

Doing physical exercise can make people happy and/as well as build up their self-confidence.

最近又看了一遍build up短语,它表示加强的意思,例句里头是build up one's confidence.所以在这里应该是挺合适的.

Sports can make people happy and strengthen self-confidence.

Working out will make people happy and confident.

sports can make you feel happy and confident
