How can I improve my endurance while skiing?

How can I improve my swimming endurance and speed?

• Hi, I'm a 15 year old boy and I've started going to the pool about two or three times a week in the last month. I didn't swim very regularly before that, maybe once or twice a month just for fun, but now I am really looking to improve my endurance and time. The longest distance I've swam is 2km non stop, that took around an 50 mins to an hour and my best time for 400 free is about 6 mins as well. How can I eat and train to improve these swims? I'd like to do a long distance open water swim somewhere in the future as well. How can I achieve my goals?

• Answer:

  You're going to hate me for this answer, but, practice. Make a daily commitment to go everyday for your set goal (I recommend an hour min. but whatever meets your personal goal). It'll take endurance and that's what you want to build up. And here is a habit I want you to get into, breath every 3 strokes until you ABSOLUTELY can't and then breath as comfortable. Breathing every 3 is a better rhythm and if you don't, you will get one big muscle on one side of your neck. It's gonna burn, and you are gonna feel as if you're gonna puke. But you need to push. Best of luck training mate.
