The present disclosure relates to the field of fitness equipment, in particular to a dumbbell bench.
A dumbbell, as indoor fitness equipment, is popular with fitness enthusiasts. In order to get a better training effect, it is a good choice to use a dumbbell bench in doing dumbbell exercises. In an ordinary family environment, the dumbbell bench takes up more space, so that a folding dumbbell bench is highly appreciated. In the current market, the folding dumbbell benches available support sitting and lying posture exercises, but cannot support some specific weightlifting actions due to lack of an elbow pad, including doing dumbbell curl and behind-the-neck press, for which the elbows need to be supported additionally. Some dumbbell benches with the elbow pad have complete functions, but cannot be folded completely. They still take up a large space after being folded, which does not allow for convenient storage. Besides, some dumbbell benches lack a locking function at the folds, and thus may structurally shake during use.
