The traditional dumbbells had a problem in having to own multiple pairs if you want to minimize time when changing weight. This would take up a lot of space in storing. The adjustable dumbbell system was created to solve this problem to a certain extent.
The latest Ironmaster quick lock dumbbell system and Powerblock Elite 90 was created to completely solve the space issue and minimize the problem of wasted time. Ironmaster is a Seattle based company which started operations in 1978. Their dumbbells are manufactured according to the latest standards and technology in the industry. If you are looking for the best adjustable dumbbells to buy I would look at topadjustableweights.com for a great place to do your research.
Most of their customers are referrals and repeat customers because of the excellent product and customer service quality offered by the company.
The handles of the dumbbells are weighing about 5lbs each and are made of solid steel with excellent welding at the ends. They are chrome plated with knurled steel for a better grip. The weights are secured through an ingenious locking screw mechanism. The disc is engraved with an OPEN and LOCK arrow for securing the weights.
The weight plates are manufactured by rugged machine iron. They are capable of withstanding some abuse such as throwing the weights on the floor. They could be stacked and interlocked into each other just like a “LEGO” piece. The set consist of 24 5-lb plates and 4 2.5-lb plates. The system will help to provide up to 75lbs resistance per hand.
In order to change the dumbbells, you must set the handles of the dumbbells on the rack with the notch on the side facing upwards. To open the locking screws, you turn the disc until the open arrow points up towards the notch of the handles and then pull the screw out. Changing dumbbells are extremely easy than most of the other systems in the market.
The Ironmaster dumbbells system is one of the most effective systems in the market currently.
I would highly recommend purchase a set for your home gym. You can literally do hundreds of exercises with dumbbells and they last forever. You will use them in every workout you do from the day you buy them.
