Of course, there is a big difference. The gym has a lot of equipment that can basically exercise the whole body muscles, as well as itinerant coaches. If you don't know the standard movements, you can find a coach to adjust them, and you can also make many friends to help each other exercise. There are many beautiful women and handsome men in the gym, all of whom are energetic to keep fit. If you only have dumbbells, it is easy to exercise. It's hard to say that your action standard is not standard. If you have no time, you can only stay at home. If you have time, I suggest going to the gym.
