Do you know the proper form for swimming? I was on the swim team...did almost 6 miles a day
The only thing I can say is just do a LOT of free style laps to build up your endurance, obviously plenty of push ups because it's mostly your triceps doing the work.
But form is really the part that's going to make or break you. My friends are stronger and faster than me on land, in water it's almost a joke.
