Girls are good at shaping and freestyle. It is easy to practice breaststroke with thick legs and full chest, and it is easy to swim butterfly with big chest, and the backstroke posture is not indecent; Freestyle method: the thigh drives the calf, the knee can't bend, the foot is slightly straight, and it swings up and down under the water.

; Pay attention to raise the elbow joint with both hands on the water, insert the palms outward, and then stroke horizontally backwards on the chest; Breathing: When paddling alternately, the head spits out 80% of the air through the nose and mouth underwater and swings the legs once. When the right hand draws the water vortex backwards, the water surface turns 90 degrees to inhale through the mouth and swing the legs once; You can also row three times and breathe on both sides. Besides swimming, you can also do long-distance running, rope skipping and yoga. Combined with fast skipping rope for half an hour every day, the effect of body shaping for half a month is obvious.
