Stretching is one of the most effective methods for thigh fitness. Two arms droop, one leg crouches below the knee, the back is kept straight, and the other leg extends backward to be parallel to the ground; Or in the same posture, straighten the other leg to the side until it forms a 90-degree angle with the body. Try to do this exercise in three groups (each group 10 times) on each leg. This kind of exercise can also be carried out when the body is standing. One leg stands to keep the body straight, and the other leg stretches backwards to make the thigh as straight as possible and parallel to the ground. Leg stretching can also be done sideways, lying flat on the bed or floor, with one leg close to the floor and the other leg lifted upward until the leg forms a 45-degree angle with the body, then supporting the thigh on a table or chair at a 45-degree angle, and then lifting the leg close to the floor to make it close to the thigh.
This exercise can strengthen the medial and lateral muscles of the thigh, instead of just exercising the lateral muscles as before, thus maintaining the balance and symmetry of the thigh.
After you have mastered leg stretching, you can try to do some "striding". Take a big step forward until the back knee is about 15 cm off the ground, and then take the other leg forward. At the beginning, it is best to do two groups on each leg, each group 10 times. Then gradually increase the number of times. Like other sports, you can slow down first and let your legs get the same degree of exercise. The advantage of this kind of exercise is that it can change the relaxation state of muscles and make the appearance look more fit.
These small exercises are very convenient and effective, and children don't have to spend money.
