Even swimmers, their daily training amount is similar, only about two hours, as long as everything is suitable, not too little, not too much. Swimming can really lose weight, but losing weight is very important and can't be done at once. We can swim once every two or three days for one to two hours at a time and last for half a year. I think it can achieve the effect of losing weight very well.
Swimming can not only lose weight, but also enhance our cardiopulmonary function, improve our vital capacity and resistance, and increase the function of pituitary gland. It can also effectively relieve the stress in our life, reduce our negative emotions, improve our skin, accelerate the blood circulation in our body and improve the flexibility of our body. If you have friends with asthma, swimming more is actually very useful for improving respiratory function and fundamentally improving our lungs.
In fact, swimming in the swimming pool for 20 minutes is equivalent to exercising on land for one hour.
Besides, if we want to have a rest, we should try to go ashore to have a rest. Don't rest in the water, because if we don't move in the water, our joints will be easily stimulated, and our body's resistance will drop, which is harmful to our health.
