Increasing muscle circumference requires several factors, and large resistance training is only one of them. In this respect, the use of equipment training is superior to self-weight training.

Exercise at home, use elastic belt, etc. , but also equipment training. Similarly, you can buy dumbbells, horizontal bars and so on. The effect is close to fitness training, which can increase muscle circumference.

But there are still differences between the two training occasions. The equipment at home is not as good as the gym, which is for sure, so the efficiency will be lower.

In addition, there are problems such as atmosphere, assistance and professional guidance, which are very different.

Therefore, it is generally possible for a person with a training foundation to practice at home.
