What are three potential ways that exercise can benefit mental well being?

1. Exercise can reduce stress and anxiety by releasing endorphins, which are hormones that act as natural painkillers and can improve mood.

2. Exercise can help to improve self-esteem and confidence by providing a sense of accomplishment and helping to build a positive body image.

3. Exercise can help to improve cognitive function by increasing blood flow to the brain, which can help to improve concentration and memory.
