I used to be a person with low self-esteem, and I wanted to escape when I encountered setbacks or difficulties. Later, I signed up for a fitness club with my classmates and started high-intensity physical exercise every day. ...

After exercising for about half a semester, I feel much stronger physically and mentally, and gradually develop a heartfelt self-confidence. The whole person becomes sunny and confident. Sticking to regular exercise can really make my heart stronger!
