Going to the gym won't work, because only a mirror can make you look stronger-so going to the gym won't work. If you go to the gym for long-term scientific exercise, it will be effective. . . . . .

Judging from your height and weight, I think your gastrointestinal function is definitely not good. It is possible that you eat a lot, but you are prone to slight diarrhea (such as drinking too much milk). If you have such a constitution, you don't need to worry, because although you need to make greater efforts than others to grow muscles with the same weight, it also means that you will basically not gain weight when you stop exercising.

I'll give you a plan. I gained about 20 pounds in three months, which is not very hard. It is suitable for beginners:

Come back on Monday (3 actions, 4 groups for each action, 8- 12 for each group)

Triceps brachii (3 movements, 4 groups for each movement, 8- 12 for each group)

Closed on Tuesday

Three shoulders (3 movements, 4 groups for each movement, 8- 12 for each group)

Biceps brachii (3 movements, 4 groups for each movement, 8- 12 for each group)

Squat (4 groups in each group 12)

Rest on Thursday

Friday chest (4-5 movements, 4 groups for each movement, 8- 12 for each group)

Forearm (2 movements, 3 groups in each movement, about 20 in each group)

Rest on Saturday and Sunday

Keeping up with 1 month three times a week will have some effect, and at least increase 10 kg in three months.

By the way, *** 10- 15 minutes before each workout is essential.

You'd better have a companion, because at first, your strength is definitely not enough, and you need someone to help and protect you.

All practical experience

If you think it's good, adopt it.
