I am as tall as you. I have been working out for two years, and now the gym is not much better than me.
I looked 37-38 when I was training for 9 months before, and my weight after 9 months was 160 kg.
My current arm circumference is 4 1cm and my weight (measured in the morning) is 174 kg.
Don't listen to their boasting, it's not congested, and the arm circumference can exceed 45, which I haven't seen in the gym. This is the average level in China.
Fitness is very hard, if there is no clear goal, it is difficult to achieve expectations.
