How to Choose the Best adjustable dumbbells for CrossFit

Adjustable dumbbells are one of the most popular pieces of equipment for CrossFit training. The reason? You don’t need a lot of space. Sure the market abounds in offers and it is not always easy to know which one to choose.

If in doubt, you should take a look at the following purchase criteria to make the best decision.

#1. Materials

If you want to play it safe, cast iron adjustable dumbbells are the most professional out there. This is the most durable material and will allow you to use the same dumbbells for many years.

Make sure that the handle is covered with synthetic rubber so that it does not bother your hands. Otherwise, you will need protective gloves.

#2. Ergonomics and Design

When exercising, be sure to seek comfort and a solid grip from adjustable dumbbells. It is not a purely aesthetic issue: you also have to prevent the pieces from slipping due to sweating.

This aspect can help you prevent muscle injuries. When buying a model, check that the handles are rough and non-slip.

#3. Accessories Included

Nowadays, certain adjustable dumbbells are included in sets that include other different pieces of bodybuilding or toning.

For example, different amounts of weight discs, protective gloves, or extra axes to form barbells that will allow you to train other muscle groups. Try to prioritize these sets to follow an integrated workout.

#4. Weight

An important question when buying dumbbells is knowing how much weight you can hold on each arm. Try household items first to find out which one is right for you.

If you want to do full-body exercises, do the squat test. Finally, if you are a beginner we recommend that you start with 2 or 4 lbs.

#5. Bar Length

Note the length of the dumbbell bar in relation to the space available. The length of the bar also limits the maximum weight at each end. For example, for 55 lb dumbbell sets, the length is usually 35 centimeters.

Take this factor into account and do not hesitate to ask other users before buying.
