What you need to know before buying dumbbells

Published on May 05, 2022

Are you thinking about buying dumbbells for your home gym, but you’re unsure what you need to know before buying them. In this article, I will tell you all you need to know before buying dumbbells from various angles. You might be wondering how many dumbbells to buy, how much weight you should buy, and whether it’s better to buy cheap or expensive dumbbells.

How many dumbbells do you need to buy?

In an ideal world, you’d buy a whole rack of different-sized dumbbells — 2.5kg, 5kg, 7.5kg, 10kg, 12,5kg, etc. But in the real world, you might be limited by space, budget, or both. So how many weights do you need? The answer depends on your goals and your current strength level.

How much weight should you buy?

The most important thing is to buy weights that will challenge you for the exercises you want to do. If your goal is general strength and fitness, start with the 10- to 15kg range and see how that feels for things like bicep curls and overhead presses. If you’re looking to build muscle, or if you’re an experienced lifter, go heavier — 25kg or more.

For a full-body workout, I recommend buying a pair of 10-, 15-, 20kg dumbbells. You’ll need different weights for different exercises: 10s are good for biceps curls and triceps extensions; 20s will make your shoulders burn on overhead presses; 30s will get your heart pumping on walking lunges; 40s will light up your back during rows.

What design of dumbbells can you buy?

You should get a hex dumbbell set; these are the most common dumbbells and probably what you picture when you hear the word “dumbbell.” They have a hexagonal shape and usually come in rubber hex dumbbells or cast iron.

Some have steel heads with a rubber coating for extra protection against damage. In general, hex dumbbells will be more durable than other options, but they’ll also take up more space, and that is why you will need a dumbbell set with a rack.

How much space do you have?

If a complete set of hex dumbbells is not within your budget or if you’re short on space, then adjustable dumbbells are for you. They work by increasing the weights in small increments until you reach your desired amount. If you use heavier weights, then fixed dumbbells are better because they don’t require the extra time it takes to adjust them between sets. However, if your workout involves lighter weights and higher reps, adjustable dumbbells may be good enough.

What kind of workouts are you doing?

If you’re looking for strength training, some dumbbells will do the trick. You can choose a pair or a set that ranges from lighter to heavier depending on how much muscle work you’re hoping to achieve. But if you’re looking for toning or aerobic exercise, it may be best to invest in some adjustable hand weights instead.
