1. Function of adjacent space: Unless family members like family fitness very much and the area of family room really lacks room for manoeuvre, when we set up a small gym in villa decoration, we must pay attention to the function of the adjacent space of the gym, and try our best to set the gym in a dynamic space in the room, away from quiet areas such as the elderly room, baby room, study room and bedroom. 2. Corresponding needs: Different people have different understandings and needs for family fitness. Therefore, when setting up a family gym, we should not completely copy other people's design ideas, but should choose fitness equipment according to our own needs and fitness direction, and design the internal structure of the gym more humanized, so as to better meet our own needs.
