As a form of aerobics, step exercise has increasingly become a popular way to lose weight internationally. The reason is that the step exercise in physical fitness test is combined with the movements and steps of aerobics and completed on a special pedal.

Therefore, it has all the characteristics of aerobics, and its height can be adjusted, so that bodybuilders can easily maintain effective exercise intensity to lose weight according to their own conditions and improve coordination more effectively. Another reason: "step movement" is safer.

Because the "stepping movement" mainly moves up and down on the pedal, there are relatively few jumping movements, which naturally makes the joints of lower limbs have obvious flexion and extension and buffering, thus greatly reducing the impact on each joint and avoiding sports injuries caused by long-term jumping to the greatest extent.

In the gym, aerobics is very popular with women. Stepping exercise is a kind of moderate-intensity exercise, which has low requirements for dancers' dance level and is suitable for a wide range of people. It is a sport suitable for modern women to improve their body shape.

Step aerobics (1968) originated in the United States and soon became popular all over the world. As a form of aerobics, step exercise has increasingly become a fashionable fitness and weight loss exercise in the world.

The main reason is that the most fundamental movement principle of step exercise is to combine the step exercise and the pace of aerobics in physical fitness test into a combined action and practice it on a specific pedal-"aerobic step exercise".

Because of the use of pedals, the action content is greatly increased, for example, the original simple steps can be changed into upper and lower boards; We can make full use of the four corners of the board and pedal to complete the connection between boards or simple board movement; You can also place the flat plate in different positions as required, such as horizontal flat plate and vertical flat plate:

We can even practice three boards with two boards at the same time if conditions permit. This provides a three-dimensional, all-round activity space for the pedal, making it diverse and more interesting.
