Going to the gym costs a lot, and the time of day is generally fixed. There are many people in it, and they can't make a training plan for you alone, so you all train together, and the progress is the same, so there should be a lot of inconvenience. However, I am free to exercise with dumbbells at home, and I can make my own training plan. Dumbbell is a very multifunctional fitness equipment, which can exercise both chest muscles and abdominal and leg muscles, so I don't think it is necessary to go to the gym.
