Your question is classic. Many people ask figuratively, just like saying I want to play football, but I don't want to join the national team.
In fact, it takes more than ten years of fitness, good scientific nutrition and physical talent to get into Schwarzenegger's figure. At the same time, the bodybuilders you meet are all in the preparation period, so their body fat is very low, and some athletes use hormones.
For ordinary people, it is already a day to be able to practice to the figure shown in the picture.
If the abdominal muscles of one finger are exposed, in fact, as long as the body fat is low, the chest, back and arms need strength exercise.
You need a reasonable long-term training plan, a reasonable diet (less fat, more protein and more fiber) and a reasonable rest.
The most important thing is persistence.
The easiest way is to go to the gym to find a coach to get started (many coaches in China are more reliable). After studying for a month or two, you can slowly supplement your fitness knowledge.
In addition, the essence of protein powder mentioned upstairs is tonic, which is condensed milk in common parlance. There is not much difference, but it is more convenient.
I hope this theme will become healthy first.
Please accept my answer. Thank you.
