Don't go to coach Liu's aerobics. Liu's aerobics seems simple, but there are still many places to pay attention to. When practicing, you must pay more attention to Liu Genghong's explanation.

Here comes the note:

1. All sports are the same, so we should take it seriously, understand that the power point should be in the right position, and tighten the core when pushing again.

2. Listen to the explanation when watching the live broadcast and standardize your actions.

It's not a one-off event to keep a good attitude and keep fit.

4. Have your own judgment. Don't be what others say.

5. Stretch properly after exercise. Otherwise, you are practicing for nothing.

Importance of core tightening 1. Change people's posture, such as hunchback, chest holding and other unhealthy bodies;

2. Stabilize the spine and pelvis, maintain the correct posture and center of gravity, and reduce the occurrence of low back pain;

3. The core area is the hub and bridge connecting the front and rear, which can construct a complete movement chain, reduce the load of joints during training and achieve the purpose of preventing injuries;

4. Strong core muscles can provide solid support for the body during exercise, thus reducing the pressure on limbs, improving the overall exercise efficiency and reducing unnecessary energy consumption.

To this end, please take time out for core training every day. Constantly activate the core muscle groups to prepare for the high-intensity improvement of the core.

Do you need to tighten the core for normal walking? Walking normally does not need to tighten the core.

Definition of core fastening:

The "core" is defined as the trunk part of our body, the area below the shoulder joint and above the hip joint, including the pelvis. Tightening refers to the important muscle groups around the body before and after the abdomen, which is responsible for maintaining the stability of the whole spine.

There are two forms of core tightening. One is called taut type, which, as the name implies, keeps all the muscles around the abdomen at a high level. The other is called dynamic stability, which stretches our trunk like a rope through the tension of neuromuscular system and myofascia to transmit strength and stabilize the spine.
