Benefits of technology

[0007]Therefore, the object of the present invention is to provide a weightlifting device that can overcome the aforesaid drawback of the prior art.
[0008]According to the present invention, a weightlifting device comprises an exercising weight that includes a handle member, an elongated adjustable member, a set of weight plates, and an elongated limiting member. The handle member has a tubular end portion. The adjustable member extends into the end portion of the handle member and is movable axially relative to the handle member. Each of the weight plates is sleeved around the adjustable member. The limiting member extends through the weight plates to thereby prevent rotation of the weight plates relative to each other.

Problems solved by technology

The aforementioned conventional dumbbell is disadvantageous in that attachment and detachment of the weight plates to and from the handle member are inconvenient.
