If you don't exercise, but at the same time you often do a good job of relieving stress, then your health and figure are usually not much different. If you can't do this, you can expect to be reborn by practicing that hour every day. This needs to be considered too much. Fitness is fitness. It can't save your bad life and solve all the problems you encounter.
3, the focus of fitness is physical health and sports performance, not bodybuilding, not the line of this ditch. If you are exercising for the purpose of "improving your appearance", you will be disappointed, because the efficiency is too low, and the effect will be better if you go out and turn left for medical beauty and plastic surgery.
4, if you want to play well, you have to take it seriously, students' science, nutrition, anatomy, sports medicine and so on. Whether it is self-study or looking for a teacher, in short, you have to spend time and energy to learn, and you can't expect coaches and apps to arrange it for you. I can draw a tiger according to the cat.
