How much do i need to swim to burn around 500 calories?

Question
Hi... i want to know how good would a 20 minute swim be for me... How much do i need to swim to loose around 500 calories? I do about 4 laps at a stretch in a 50 meter pool..... do you think this is good enough or should i increase the number?

Answer
Ruchika,
The exact amount of calories a person burns as related to physical exercise varies from person to person.  I am not a dietician or medical expert.  They would be the ones who can answer that question much better.  This will also depend on how much energy you exert while swimming.

I will say that you should always be striving for increasing your abilities.  Swimming 4 laps is GREAT.  However, try increasing it to 5 over time.

I am sorry that I am not much help in you question.  I am an expert in swimming training, mechanics, and sport-related questions.  Burning calories is more of a health-care related question.

Best of luck.
