What barbell is on the left? Is it the same as the one on the right? I feel that the sides of the barbell on the left seem to be fixed and I can't take it off. Solve it, thank you.
On the left are curved barbells and straight barbells with fixed weight. The one on the right is a combination of barbell pieces with different weights. The reason why there is such a barbell with constant weight is to prevent people from being crowded and the equipment can be used normally. For some muscles, this length is more suitable for exercise. Moreover, if the weight is placed at will, the gym will have to buy more barbell pieces, which wastes too much cost, so there will be barbells with this combined weight.
