10. What are the important features in the handle of the dumbbell?

The handle of the dumbbell is equally important as its head. This is because it is the part that will be used to carry out the exercise. The following are the different aspects of dumbbell handles that you should carefully analyze:

Material

The handle of a dumbbell is made up of metal. It is durable and heavy-duty. However, you might find rubberized handles as well. You should avoid them at every cost since they are not durable and difficult to maintain. 

Diameter

The diameter of the handle plays an important role in determining its grip. Thinner handles do not provide comfort because the weight is not evenly distributed in different points of grip. Generally, a diameter of 1 to 1.5 inches is considered efficient. However, for heavy-weight dumbbells, it can go up to 2 inches. 

Texture

The handle of the dumbbell should have knurling on it. It provides efficient grip and prevents slippage, reducing the chances of injury. Usually, every manufacturer provides dumbbells with knurled handles. But make sure to check it out. 

Besides, knurling can be deep or shallow. Shallow knurling does not hurt but it does not provide efficient grip. On the other hand, deep knurling gives perfect grip, but it can be tough on hands. 

This texture is very important, especially in heavy-weight dumbbells. The following are the different types of knurling that a dumbbell can have:

• Volcano Knurling
• Mountain Knurling
• Hill Knurling

• Check the difference between the marked weight and the actual weight of the dumbbell. Usually, an error rate of 3% is acceptable. However, quality manufacturers provide dumbbells with an error rate of 1% only. 
• Check the smell of rubber. If it is too pungent, the quality of rubber is poor. 
• Check the finishing of the dumbbell. In the case of rubber dumbbells, the thicker the coating, the more durable it will be. 

12. Does the dumbbell set come with a rack?

No, the dumbbell set does not come with a rack. However, some manufacturers might offer you discounted deals if you buy both items. Make sure that the size of the rack can hold all dumbbells in the set.
