Breathing and heartbeat play a "boiling effect", and how many meters you swim varies from person to person. Women and men are different from person to person.

At first, you can only swim continuously 100 meters. I have practiced for two years, and now I can swim 2000 meters continuously. But 2000 meters is too tired, and I feel that my 1000 meters is almost effective.

You should stick to it. Don't stop swimming for a while.

Every time you set yourself a new goal challenge, it's best to look at time and seconds. If you make progress, you will lose weight!
