If you are thinking about starting a new fitness routine, the best selling Cap Barbell 40 lb dumbbell set could be a useful addition to your home gym.

Design features

Cap Barbell 40 lb Dumbbell Set

If you are thinking about buying a new dumbbell set, you will usually have 3 main types to choose from; adjustable, fixed weight, and those that require weight plates.

While each type has their benefits, the Cap Barbell 40 lb dumbbell set provides you with weight plates and a set of bars to allow you to adjust and store the weight easily.

With most dumbbell sets of this type, it’s often difficult to find a way of storing the weight plates without buying an additional weight plate storage tree or rack.

Fortunately this particular set includes a carry case complete with handle, making it easy to keep the set together for both storage and transport.

In terms of the bar and collar design, knurling has been added to the handles to help make them easier to grip, with spin-lock style collars used to securely hold the plates in place.

Although this set provides you with 40 lb of weight including the bars, additional weight plates are available for when your strength level increases.

Exercise options

Together with a standard or Olympic barbell, having a high quality set of dumbbells is one of the most cost effective ways to build strength and muscle from your own home gym.

Where many adjustable dumbbells are often too long to perform curling exercises comfortably, the length of the bars in the Cap Barbell 40 lb dumbbell set makes them ideal.

As well as standard dumbbell curls, there are a much wider range of exercises that can be performed for both upper and lower body muscle groups.

When combined with an adjustable weights bench, the following list is just a few of the more popular exercises that are possible:

  • Incline hammer curls
  • Concentration curls
  • Incline dumbbell flys
  • Dumbbell rows
  • Tricep kickbacks

  • Side lateral raises
  • Dumbbell lunges
  • Front raises
  • Lying tricep extensions
  • Forearm curls

With 30+ exercises to choose from, this set allows you to work each muscle group from a variety of angles to help develop a well balanced physique.

Review Overview

Overall Review Rating

4.5 / 5

Being supplied in the sturdy plastic carry case, this allows you to keep the Cap Barbell 40 lb Dumbbell set organized and accessible when not in use, as well as easier to take with you if needed when travelling.

While their design is simple, they remain one of the most economically priced and popular dumbbell sets available, being designed with ergonomic grips for high-performance comfort.

The durable cast iron plates have a semi-gloss finish for long-term rust and maintenance-free use, with collars that are threaded for a safe and secure fit to the handles.

The carry case is not bulky, measuring just 20 inches long by 9 inches wide, and weighs 41.15 pounds in total.
