Dumbbell Set Features
What do you look for when buying a pair of dumbbells? first and foremost ensure you have a clear fitness goal in mind. Purchasing a dumbbell set for home use is a great way to start your reaching your fitness goal. Buying a pair of dumbbells is more pratical than buying just the one.
If your fitness goal is to lose fat then two 10kg dumbbells are more than enough. However if your goal is to put on muscle, a pair of two 10kg dumbbells are a good start but at some point in time you will need to progress. This is why you need a dumbbell set that allows you to adjust the weight discs. When you become stronger the dumbbells must have the capability to add on more weight.

It is also vital before buying a dumbbell set to know the diameter of the bar. This is so that you can add more weight when required in the future. Progression is the key to getting stronger and for muscle mass gains. Do not buy a set of fixed dumbbells if getting bigger is your goal.
Below we have explained briefly the features that make the best set of dumbbells:
Weight Disc Plates
It is wise to know the breakdown of weight discs included in the content box of the dumbbells. This way you can plan how much weight you can increase the overall weight by. You might find that some exercises that work your deltoids (shoulder) will initially require less weight. After time you slowly increase the weight to improve.
Bar Diameter
The bar diameter is another crucial component to be aware of. With fitness progression you will need to add more weight at some point. Therefore it’s important to know if other weight disc brands can also fit the dumbbell.
Once you know the bar diameter and you buy any weight disc that fits the bar, however you don’t want to buy anything too big in diameter as the disc will rattle about during your workout.
Bar
This feature simply refers the amount of bars included in the content box and the length.
Material
Certain materials are more durable than others. This feature we state the material of the bar and the weight disc itself. The materials are generally cast iron and some sort of plastic.
The advantage of cast iron is its durable physicality however depending on environment cast iron can rust. If you keep the cast iron dumbbells in the garden or a damp shed then the dumbbells are prone to rust over the years.
The advantage of plastic dumbbells (vinyl) is that they will never rust but they cannot take as much beating as cast iron dumbbells. So don’t throw the dumbbells to the ground during your workout sessions.
Additional Features
Here have highlighted anything that is unique to the particular dumbbell set. For example some the dumbbells come with a case which is extremely handy to keep things tidy. This is extremely useful for parents keeping potential heavy objects away from children and also for those travelling that want to workout in hotels.

This dumbbell set can also be converted into a barbell therefore creating versatility in your training routine. Dumbbells provide better range of motion for most exercises where barbells allow you the work the muscle differently which stimulates more growth and burns more calories.

Best Dumbbell Set #No.3

The weights are very good and its a real cast iron, not dust or things like that.
The extender is a big plus, its very good.
The handles are great as well!

York Cast Iron Dumbbell Set
Worth it for the dumbbell bars alone. Absolutely fantastic grips, way better than any i’ve used in gyms or at home. I’d definitely get some more weight discs in addition to this though, as 10kgs will not take you far.
