60 kilograms. How tall are you? Now boys are still quite tall, estimated at 170. If so, you will be thinner. )
First of all, exercise is a beating process that consumes a lot of energy. If you are too thin, the effect of exercise will not be very good.
I'll give you some advice on how to regulate your stomach in your diet.
1 Eat more onions (see the role of onions and garlic in the encyclopedia)
2 Eat more garlic (it is best to mash raw garlic and leave it 15 minutes)
3 balanced nutrition (breakfast must be eaten properly, and snacks should be carefully guarded against junk food)
In sports, because you are thin and not suitable for sports for the time being, I will give you some advice.
1 First, go to the gym and run 2000km to exercise your hands and feet (just jog at a medium speed).
2 Stretch your hands and feet after running, and then do 2-3 sets of dumbbells at an interval of 1 min (the movements must be standard).
3 Do sit-ups after the dumbbells are finished, and the number of 2-3 groups is also 15-24 (don't compare with others at your own pace).
Do bench press after finishing .. It may be a little difficult to master balance at the beginning. Don't use dumbbells, just push with iron bars.
Exercise is 7 points, 3 points and persistence.
