Action (accuracy, proficiency, strength and physical coordination, as well as the speed, amplitude and frequency of action).

Two: rhythm (the rhythm and movements of body jumping should be in tune).

Three: music (music must have a tacit understanding with action, and the strength is symmetrical with action).

Four: Fitness (aerobics is originally a set of bodybuilding gymnastics, which has derived a lot of movements, but it is ultimately aimed at fitness).

The basic steps and essentials of aerobics are:

(1) step. The thighs are raised horizontally and the calves are naturally drooping. When landing, use the forefoot to transition to the whole sole, and the arm swings back and forth naturally to keep the body natural.

(2) Turn the jump on and off. Jump and land separately, hips and toes open, knees bent in the same direction. When stepping on the ground, the heels are close together and the knees are cushioned. The movements should be ups and downs, coherent and elastic.

(3) kick and jump. Strength legs bend your knees and swing back, knees should be close together. Don't use too much force when bouncing forward, and control the movement and extension of knee joint and hip joint. Then do it with the other leg.

(4) kick and jump. One leg bends and swings back, and the hips and knees are in line. In the process of running and jumping, the knees and ankles are fully buffered and the arms can swing naturally.
