The Best 20 Kg Dumbbell: Our Picks

Buying and Evaluation Criteria for 20 Kg Dumbbells

When buying a 20 kg dumbbell there are a lot of things to consider. Besides the usual aspects such as the length of the bar, you also have to pay attention to the material of the dumbbell.

In summary, these are:

In the following section we have summarised for you what is important in the individual criteria.


The material of a dumbbell can make a big difference to its stability and quality. You should make sure that you use harder materials. Good materials for the barbell are cast iron, steel and chrome, which withstand higher loads and are excellent for you if you want to expand your 20 kg barbell.

A stronger material allows for more weight on the barbell.

If you don't want this, you can use hard plastic. There is no right or wrong with the material for the weight plates, but if you still want to lift more weight, cast iron and steel are worthwhile because they are heavier than fillings with sand, water, etc.

Also note that many dumbbells have only one alloy, which makes the material stronger but not heavier. This can be both an advantage and a disadvantage depending on whether you want a stronger muscle stimulus or a weaker muscle stimulus.


The length of a 20 KG dumbbell differentiates the dumbbells in their various types, e.g. barbells, dumbbells, kettlebells, aerobic dumbbells. The different lengths of the dumbbells allow you to train different muscle groups in a targeted manner.

Dumbbell for shoulders and biceps, barbell for back and biceps. The length of a dumbbell also affects the price of a dumbbell - as a rule, barbells cost more than dumbbells.

Aerobic and kettlebells are the smallest / shortest dumbbells with which you can train your flexibility.

Expandable / non-expandable

Expandable dumbbell means that additional weight plates can be attached. This allows you to continuously expand the dumbbell according to your training. However, there are also dumbbells that are not expandable.

Extendable dumbbells allow for a long use

Here you have to decide whether 20 kg is enough for you or whether you will need more weight in the future. It is important to mention that more weight triggers a higher muscle stimulus, but you should not overdo it with the weight because the training form can suffer and you can injure yourself.
