When swimming, people's metabolism is very fast. You can consume 1 100 kilojoules of heat in 30 minutes, and this metabolic rate can be maintained for some time after you leave the water. So how many meters can swimming last to keep fit effectively?

According to the usual practice, experts suggest that healthy people under the age of 35 should swim for 2000~2500 meters at a time; For people aged 35-50, the swimming distance should be 1500-2000m. Older people over 50 years old should choose 800 ~1200m according to their physical condition and swim 4~5 times a week. If you persist for 3 months, you will definitely have a good slimming effect.

Besides, don't swim for too long. Soaking in water for a long time is very harmful to the skin, and it is not moving in the water, which is easy to stimulate the joints by cold and reduce the body's resistance, which is not conducive to fitness.
