I have decided to add some lap swimming into my routine as it is summer and I go to a gym that has a pool. The only problem is that I have never really done lap swimming before. I know how to swim and the last time I took swimming lessons was when I was about 8 years old. What I would like to work on is my technique so that I can become efficient about using swimming as a means to exercise. I have tried searching on the web and I haven't found anything that fits my needs.
So, my question is, does anyone have any information on swimming as a means of exercise and different techniques/tips and styles to use and ways to improve your swimming especially if you are someone who hasn't "seriously" done it?
