Should you wear flippers while swimming?

It depends. If you are trying to improve a certain stroke such as butterfly, it can help you get your technique down. Leading to a faster swim time. They can also strengthen muscles more than without them. One the flip side, all they do other then that is make you faster with them on but without you will most likely be the same speed. They can also simulate the feeling of going faster which for some people helps them in the pool.
