Meet your home gym’s new core weight stack

PowerBlock dumbbells are more than just weights — they’re the foundation of a fully adaptable strength training system. With the ability to attach EZ curl or Straight Bars, you can instantly shift into presses, rows, or curls. Add a kettlebell handle, and your dumbbells transform into a whole new training tool.

This is true workout flexibility: one compact set that evolves with your goals, supports full-body training, and eliminates the need for dozens of traditional weights

3rd time ordering online to supplement a pair of USA Elite 90’s I’ve had for over 12 years. Drug them across the country with military moves. Still working well and ordering parts is easy and efficient on the site

I'm 68 years old and have been strength training for most of my life, in one form or another. I have a gym in my basement and have been using Powerblocks for more than 10 years. I've seen many other types of multi-weight dumbells and have never seen any that are as reliable, adjustable and easy to use as Powerblock. I recently dropped one of mine and the elastic cord that holds the adjustment piece in place broke. It was simple and easy to order a new one. Installing it was a breeeze also.
I'm a huge fan....and I have no stock in the company, btw.

I heard about PowerBlock while browsing through Reddit and read nothing but great things. I wanted to purchase some weights for my husband, and from what I read, PowerBlock was the perfect fit due to how they make their products. I was definitely sold, even though I wasn’t the one to lift the weights. The shipping was on time as indicated when ordering. When I had an inquiry, the service team was speedy in responding. (They were also very friendly). In the end, I have a very happy husband. Overall, you can tell how much innovation went into the creation of the weights! I definitely foresee ourselves ordering more from PowerBlock. Thank you, PB team

I have several sets of dumbbells but having recently had shoulder surgery I needed some lighter ones for my shoulder I was rehabbing. Rather than by standard dumbbells I decided to go with Powerblocks. I really love them. They adjust very quickly and I can go heavy in one hand an lighter in the other.

You really cannot go wrong with Powerblock selective dumbbells. I have researched extensively, and although most of the others are built with an easy-turn handle to adjust the weight, there have been issues as the handle eventually does not grip the right Weight. With PowerBlock, they are built so that the weight you choose will always be the right weight. Build quality is like a tank, and they feel good. All selective dumbbells make some noise when using them. As you do curls, as an example, you will hear some noise from the weights, but it's nothing to worry about. If you want a durable, long-lasting set of dumbbells that provides you with a great workout, I would invest in PowerBlock. In my opinion, you cannot go wrong.

We have three sets of power blocks. Two at our gym and one at our lake place. When traveling we throw a set in the rv. Great product. Great customer service. Use them daily for years. No issues.
