How many 25 meter lenghts would you have to do to burn 5000 calories?

Question

In swimming, by the way. And also what stroke is best for burning calories (not butterfly, though).

Thanks~

Answer 1

5000cal=2 lbs

Really working it and eating right 1 week.  Keep your heartrate up, do some kicking.  Swim for at least 30 minutes 3X a week

Answer 2

way to many.... we are talking several days worth of swimming here

Answer 3

you'd have to swim for ages to burn that many calories.

the best stroke to loose weight with?? is debateable. as a coach, i can tell you it's better to alternate between freestyle, backstroke and breaststroke and to swim for a minimum amount of time or laps. start with 20laps of a 25m pool. do it slowly, change strokes or do kicking but don't stop, as it gets easier, you make it harder by swimming it faster or for more laps, etc.
