Simple repetitive movements are widely circulated.

skill

Running, brisk walking, mountain climbing, cycling and so on are all simple and repetitive exercises. These are the things that everyone is most willing to do, because it is simple and the threshold is low. If you just use this kind of exercise to keep fit, there are actually many hazards, including:

1, articular cartilage (such as knee and waist) is heavily worn.

2, tendon inflammation, adhesion

3, strengthen the wrong posture

4. Excessive pressure on the heart and blood vessels.

5. Repeated exercise will lead to a continuous decline in energy consumption and metabolic rate of equal exercise.

Competitive sports replaced scientific fitness.

skill

Competitive sports are aimed at the sports themselves (such as running, swimming, skiing, etc. ) and pursue higher, faster and stronger. Body-building refers to that after evaluating the basic qualities such as heart, joints and muscle strength, athletes design training contents according to their own physical conditions, aiming at improving their cardiopulmonary function, coordination ability, strength level and endurance level, and constantly re-evaluate and adjust them. Start "competitive sports" without doing "fitness exercise" Because you have no idea about your state and level, you don't rule out the possibility of practicing well, but it is more likely that you have practiced all by yourself.

Don't consult a professional

skill

There are specialties in the industry, so don't be blind and confident, and don't trust professional experience. The best way to avoid pain and waste time is to find a professional, not necessarily a coach, maybe a world champion, maybe an expert in sports, or someone who practices well. These people will have a lot of valuable experience and will save you a lot of detours. A good experience is relatively a shortcut. Sometimes, blindly staying in the gym for a few hours may not have a good effect. In the gym, there are always few people who practice well. Many people think they practice well, but in fact it may be because there is no reference standard.

Have no opinion of yourself.

skill

Know yourself and yourself. For fitness, knowing yourself is to make a scientific evaluation of yourself, including basic strength, posture, endurance, coordination and agility, joint strength, joint range of motion, cardiopulmonary function, reserve heart rate, metabolic rate, skeletal muscle content, body circumference, fat ratio, visceral fat level and so on. If you don't know all this, start practicing. The most direct result of this behavior is a waste of time, and the serious one is injury. Without scientific evaluation, starting training at an inappropriate level will not only fail to achieve the expected results, but may also make people feel strongly frustrated and even give up.
