I'm looking for help to improve my swimming endurance.?

Question

Currently I can swim 400 meters in the pool, but I'm struggling.

I need to build up to at least 750, if not 800-1000.

Any advice from swimmers is greatly appreciated.

Answer 1

I am a swimmer and i swim distance the best thing you can do is swim as much as possible even if not all at one time if you can only swim a 400 swim a 400 then 20 min do it again its going to be pretty painful but you will get there during the summer we are doing 9000 meters a day so it really does just take a lot of work and stick with it!!!!

Answer 2

running helps improve stamina, but the best way to build up is do more yards everyday.  don't slack off just keep swimming.
