Answer: I began to like physical exercise and fitness when I was a freshman. At that time, limited by conditions, it was mainly long-distance running. But over the past few years, I have accumulated a lot of fitness experience and knowledge to protect myself in fitness. The answer here is from several aspects, and what should be paid attention to in scientific fitness.

(Every point is extremely important)

First, warm-up exercises.

This is a point that many beginners easily ignore, but it is also the most critical point for scientific fitness and protection of their bodies. Many beginners may want to exercise as soon as possible because they don't have much time or patience, and ignore the importance of warm-up. How important is it to warm up? Let's just say that if you like playing basketball, if you play basketball before warming up, you will definitely have various problems in your body within six months, which will make you unable to play basketball. If you throw a few balls every time you play, run a few steps, stretch and play again, it will be no problem for decades.

Second, the posture standard

This point is often overlooked by many bodybuilders after they get started. Because in their view, they may want to pursue the standard posture, need too much experience, and they can't adapt themselves, so they give up. However, posture standards are very important. In fitness exercise (muscle building exercise), posture standards can ensure that our muscles are not tense when we turn off the phone. On the other hand, it can also ensure that we can stimulate muscles more effectively, make muscles more symmetrical, and there will be no situation that the left arm is thick and the right arm is thin, or the left chest is big and the right chest is small. For running, scientific running posture can help us use our bodies more efficiently, and can also ensure that our bodies (especially our knees) are not injured.

Third, sports equipment.

Sports equipment sometimes plays an important role in sports, especially shoes. In long-distance running, a pair of professional running shoes can cushion the vibration and help us protect our knees. If you wear hard-soled shoes, it is easy to wear your knees when running. If you run for a long time, it is easy to get hurt, and knee injuries are often irreversible. Or in basketball, a pair of professional basketball shoes can protect our ankles, so that we won't get hurt in intense sports. As for sports equipment, we should not save money on some necessary equipment.

Fourth, reasonable exercise intensity.

Some friends may want to challenge themselves, or be too confident in their physical fitness and blindly improve their exercise intensity. If it exceeds the body's endurance, it will be injured or even life-threatening. We should arrange the intensity reasonably according to our own level in sports. You can't blindly increase your strength.
