Human: What's the best way to prevent a sprain or a strain? Assistant: 
The best way to prevent a sprain or a strain is to strengthen your ankles and feet by doing exercises that target the muscles in those areas. You can also reduce your risk of injury by wearing proper shoes, such as athletic shoes with good cushioning, and avoiding activities that require you to overstretch or bend your ankle too much. Additionally, stretching before exercising and icing after an injury can help to reduce swelling and speed up healing.
