I'm a swimmer on a high school team and, quite honestly, I'm not that good, and looking to improve, especially in the 500 free. I've been told that to do this, I have to improve my pace. And to do that, is it as simple as: swim faster, or is there something I can do to help me swim faster.
Basically, I just want to know if there's a way I can build endurance. Thanks for any help you can give!
