I just learned this question seriously recently, so I'll give you an answer here. First of all, you should know the principle of building a big body by fitness. When you say building a big figure, you also mean building muscles, right? What is the principle of muscle training? When you go to the gym, you can exercise your muscles by practicing gym equipment or doing push-ups and sit-ups at home. When you exercise that part of the muscle, the muscle will be torn and torn, and then when you exercise and rest, the muscle will repair itself. At this time, eating is very important. You must eat enough protein and other nutrients to provide enough energy for muscle self-repair.

The advantage of being in the gym is that there are many different equipments in the gym. Different equipment exercises in different places, which will tear muscles in different places when you use it. So when you have your own ideas, it will be better for you to go to the gym. What do you mean by your idea? That is, you know where you need to increase your muscles, where you want to be a big man, and you have a certain understanding of every equipment in the gym, where to exercise your muscles, and so on. This doesn't mean that you can't be the big guy you want at home. Although exercising at home has certain limitations, its advantage is convenience. You can buy a yoga mat, dumbbells and other gadgets, do push-ups and sit-ups at home and so on. You can also learn some movements online with dumbbells and become a big guy.

If you want to get the figure you want, the most important thing is to stick to it and find a way that suits you. It's no use not insisting. You can practice at home if you have less time. It's up to you whether you have time or not, but you must stick to it and finally make fitness your habit.
