III. Fixed Dumbbells VS Adjustable Dumbbells: The Comparison
Both fixed dumbbells and adjustable dumbbells are suitable for training muscles and gaining strength. But they are varied in properties and functions. In order to facilitate your understanding towards them, Speck has made a comparison between them.
3.1 Construction and Durability
The most obvious difference between the two kinds of dumbbells is the construction, or the way they are organized. Fixed dumbbells can not be separated unless they are broken, and there is no weight plate on a fixed dumbbell. In other words, the weight of such a fixed dumbbell has already been set by the dumbbell manufacturer. On the contrary, you can take down weight plates of an adjustable dumbbell easily with the help of shifting mechanisms.
The way these two kinds of dumbbells are assembled is closely related to the durability. Fixed dumbbells are often made by iron steel and chrome inside, and are coated with a layer of rubber to achieve better grip and protective function. There is no moveable part in fixed dumbbells, which means these dumbbells can not be easily dismantled. In fact, quality fixed dumbbells are designed to be used for a lifetime. And if it is a dumbbell made by solid and robust stuff such as cast iron, you can still use it even the ends are slightly damaged. But if a broken dumbbell is filled with sand or water, you should discard it as the weight can not be maintained for good.
Although the adjustable ones are space-saving and money-saving, when it comes to durability, they are overshadowed by the fixed counterparts. Because adjustable dumbbells need a locking system that is in charge of the adjustment of weight plates, they may become metal scraps when the shifting mechanism is damaged totally. In addition, despite the fact that adjustable dumbbells are often made by robust and tough material, the weight plates connecting system inevitably contains parts made by plastics, which may wear down or suffer from frequently heavy use and aging as time goes by.
Compared with fixed dumbbells, adjustable ones do a better job in terms of flexibility. In general, quality and good-sized adjustable dumbbells provide users with weight plates weighing from 1 kg to 20 kg! The flexible choice of weight plates enables you to train every part of your body, and can meet your whole family’s workout requirements.
In contrast, fixed dumbbells are lack in flexibility and can limit your exercise intensity. In other words, if you want to augment the weight or train some other fragile parts of your body, you have to visit online retailers or go to local shops to purchase new dumbbells. Another spending, right? Even though you feel as if you do not have to adjust the exercise intensity, your body does not tell a lie. The body may have already got accustomed to it and your daily exercising becomes minimally effective.
Undoubtedly, it is way more convenient for you to choose a pair of dumbbells of fixed weight than to frequently adjust the weight plates of adjustable dumbbells. Some exercisers even have gradually cultivated their exercising habits, hardly tolerating the interruption to their dumbbell workouts. According to a gym report, about 73% of the surveyed said that they would like to use fixed dumbbells in the gym so that they would exercise at a stretch to their hearts’ content.
Another thing they worry about adjustable dumbbells is the locking system that controls the adjustment of weight plates. Since most of the intricate mechanisms are made by plastics, the quality of adjustable ones can not be 100% guaranteed. And those dumbbell fans are afraid of the breakage of the plastic parts, which may cause weight plates to fall on the ground or even hurt themselves seriously.
3.4 Storage and Space Efficiency
Where to store dumbbells has been vexing home-based dumbbell exercisers since the outbreak of the Covid-19. Fixed dumbbells often occupy many space of the house. Some people even place dumbbells fully under the bed due to limited space. However, if it is a pair of adjustable dumbbells, when not exercising, you can simply collect all the weight plates together with the handle and put them in a place less than just 1 square meter. As mentioned above, adjustable dumbbells have advantages in space efficiency. By adjusting different weight matches, people can do workouts based on different training intensities with only a pair of dumbbells!
3.5 Price and Cost-effectiveness
As you may have known, adjustable dumbbells are much more expensive due to a complete set of weight plates options, whereas fixed dumbbells cost you less. However, in the long run, if you want to build up your muscles with increasing training levels, buying adjustable dumbbells are definitely more economical and cost-effective. In this way, you do not have to buy fixed ones from time to time, instead, your money can be used to pick up other household fitness equipment such as a treadmill or a rowing machine.
