1, it is ok to do push-ups and sit-ups at home, which can play a role in exercising, but it seems a bit simple to do only the above two actions if you want to improve your physical fitness in an all-round way.

Dumbbells can exercise muscles in many parts of the body. However, due to the different strength levels of various muscles in the body, dumbbells with fixed weight are not suitable for exercising the whole body muscles. Unless you have dumbbells of various weights, you can choose dumbbells with adjustable weights for your own use at home.

3. The gym is well-equipped and has various training courses, which is very suitable for systematic training.

4, sit-ups and push-ups can exercise muscles, but because the intensity is not too great, the effect of muscle gain is not particularly obvious, but if you persist for a long time and increase the intensity (as my brother upstairs said, do push-ups in various positions), you can still gain muscles, but you can't reach the figure of those muscular men on the Internet.

You can't do push-ups after practicing dumbbells, which proves that your physical fitness is still not very good and needs to be strengthened.

Second, my suggestion:

1, in addition to push-ups and sit-ups, you can also deepen squatting (increase weight with dumbbells) and hard pulling with dumbbells (specific action demonstration can be Baidu) at home. You should do dumbbell bending, right? This combination: push-ups mainly practice chest muscles and humerus, sit-ups practice abdomen, squats practice legs, and dumbbells pull the waist hard (waist strength is very important for men). In the process of your continuous exercise, your strength and muscles are enhanced, and you will find more ways to exercise. For example, when you take a shower, the water heater will have a piece of cold water. You can connect cold water with a bucket and lift it a few times as a dumbbell.

2. You can choose a gym if you have time and economic conditions, because there are many equipments in the gym and the load can be adjusted. In fact, if you want to increase your muscles, the way of big weight and few times (number of groups) is much better than the way of small weight and many times (number of groups). Training at home is because the load can't get up, so the muscle gain effect is not obvious. At best, your muscles are clearer.

Besides scientific training, we need to pay attention to rest and diet. When doing weight-bearing training, muscle fibers will be overwhelmed and torn. At this time, it will take time to repair. After the repair is completed, the muscle fibers will become thicker than before, which is the reason for the muscle enlargement. Therefore, in addition to exercising your muscles, you need to let them rest and recover. In addition, diet is also very important. After increasing the amount of training, it is impossible to supplement enough nutrition, and it is impossible for horses to run without eating grass. Moreover, muscles are made of protein. Without enough protein, muscles can't grow.

I hope it helps you. If you are not clear, you can write to me at the station.
