[0002] Dumbbell benches are fitness aids commonly used to assist dumbbells in performing essential exercises such as incline dumbbell bench presses, decline dumbbell bench presses, and flat dumbbell flyes. Using dumbbells can improve joint and muscle control in various parts of the body, train smaller muscle groups surrounding the target muscle group, and effectively stimulate muscle tissue at the junctions of different muscle groups. The biggest feature of folding dumbbell benches is their foldability, allowing them to be easily folded away when not in use, greatly saving storage space. They can easily fit in both home gyms and small gyms. Current folding dumbbell benches use hinges for rotation and folding, and pins and holes for overall support. However, existing folding dumbbell benches rely on pins, holes, and hinges for folding and unfolding, requiring frequent folding and unfolding operations. Frequent insertion and removal of the pins within the holes can lead to decreased fit, affecting the overall stability of the dumbbell bench. Therefore, we propose a new folding dumbbell bench.
