Action 1 Walking sideways in the water: Open your feet to the left and right, about a little wider than your shoulders, and open your hands and arms on both sides of your thighs to help balance your body. Then the right foot moves laterally behind the left foot, so that the legs cross, then the left foot opens to the left, and then the right foot moves laterally behind the left foot. After crossing your legs for about 25 meters, change your left foot and step back, so that the resistance of water can tighten the muscles inside and outside your thighs.
Action 2: Start squatting in the same place: feet and heels are close together, knees are slightly bent, hands and arms are raised forward to shoulder height, and arms and palms are flat on the horizontal plane. Then stroke the arm down to about 45 degrees behind the thigh. At this time, you will feel your body jump and stand on tiptoe naturally. Pull up your arm and let your body sink until your arm is flat on the water. Repeat the whole set of movements 30 times to modify the arm lines.
If you really want to slim your legs by swimming, you can refer to the following four tricks:
In freestyle and backstroke, the legs are whipped up and down alternately, while in butterfly, the legs are whipped at the same time. Let's look at the action pattern of breaststroke. First of all, the waist, abdomen and thighs exert force at the same time, and the calf and the inner side of the foot push the water at the same time, outward, backward and downward, and then inward and upward, just like drawing a semicircle. The outward water pushing and inward water clamping are continuous, that is, the belt clamp is pushed continuously. Among the four strokes, only breaststroke uses kick clip and kick clip. The former can make the leg curve smoother and longer, while the latter can strengthen the leg strength and improve the metabolic rate.
Look at the table below to fully understand the utilization rate of leg muscles in the four strokes.
The quadriceps femoris is in the front of the thigh, the biceps femoris is in the back of the thigh, the gastrocnemius is in the back of the calf, and the gluteus maximus is the main muscle of the hip. Among the four strokes, butterfly, freestyle and backstroke are only used in part. Only breaststroke can make full use of these muscles and fully move the legs. It can be said that it is the perfect stovepipe weapon for four strokes.
Extended data:
Breaststroke is a swimming posture that imitates frog's swimming action, and it is also the oldest swimming posture. In breaststroke, swimmers can easily observe whether there are obstacles ahead and avoid hitting them. Breaststroke is one of the competitive swimming postures. The human body is prone on the water, with two arms bending and paddling under the symmetrical straight arm on the chest, and two legs bending and stretching symmetrically to catch water, just like a frog swimming. Breaststroke is labor-saving, durable and of great practical value. It is often used for fishing and hunting, swimming, rescue, water treatment and so on. At the same time, it is also a learning project for beginners of swimming.
