Let me explain the difference between quick adjustment dumbbells and regular dumbbells:
Conventional dumbbell types
At present, in addition to conventional styles, dumbbells on the market also include hand bells, kettlebells, hexagonal dumbbells, interchangeable weight adjustment dumbbells, and so on. They are versatile and can be classified into fixed and adjustable types.
This type of dumbbell is made by pouring pig iron in one go, with a central iron rod and solid iron balls on both sides. The surface coating material is mostly impregnated plastic, baked paint, and glue. The advantages are good hand feel and easy to use.
After completing a set of movements and taking reasonable breaks between groups, one can immediately switch to the next set of weight exercises. This not only results in more even distribution of strength and higher training efficiency, but also allows for easy throwing down after use (saving time). That's why gyms use fixed dumbbells.
If there is not enough exercise space at home, adjustable dumbbells should be more suitable for you.
A set of adjustable dumbbells includes a barbell bar, counterweights, and dumbbell clips. The material is mostly cast iron, wrapped with electroplating, baking paint, and adhesive. Therefore, its characteristic advantage is that it can be used as multiple dumbbells by changing the weight, which is affordable, space saving, and cost-effective.
Analysis of the principle of quick adjustment dumbbell
The dumbbell is composed of three parts: handle, dumbbell plate, and tray
The tray is used to place and store dumbbells, but please note that you need to press the dumbbells against the safety lock in order to change the weight.
Dumbbell pads are used to change the weight distribution during exercise
The handle can be regarded as the core of the entire dumbbell. In addition to the mechanical spring, the elliptical irregular steel frame on the handle is used to rotate and clamp the dumbbell pieces for weight replacement.
