Traditional dumbbells take up a ton of space and cost a lot more in the long run. A full set can easily run into the thousands. Even the rack to hold them can sometimes cost more than an entire set of PowerBlock dumbbells!

PowerBlock dumbbells replace an entire rack with a single compact set, saving you both space and money. They adjust in seconds, offer a wider range of weight options, and can grow with you through optional expansions and accessories like kettlebell handles and barbells.

Don't let the look of them deceive you, they are built VERY tough. PowerBlock offers both commercial and residential grade options which use the highest quality materials. They’re durable, quiet, and perfect for any gym setup where space is limited. Rid yourself of the cost and clutter which comes with traditional dumbbell.

PowerBlock revolutionized the strength training world with a game-changing idea: adjustable dumbbells that save space without sacrificing performance. Born from the frustration of cluttered gym floors and overcrowded home gyms, PowerBlock was created to simplify serious strength training—without the need for an entire rack of traditional dumbbells.

The story starts with Carl Towley, a lifelong fitness fanatic who grew up inspired by bodybuilding icons and built his first DIY weights out of coffee cans and a broomstick. After years working in gym equipment repair and launching his own small fitness company, Carl recognized the same issue at gyms everywhere: dumbbells took up too much space. That sparked the idea. After countless prototypes and a late-night “aha!” moment in Santa Cruz, the original adjustable dumbbell was born—and PowerBlock was officially founded in 1993.

From its humble beginnings in a cold Minnesota workshop, PowerBlock grew into a respected name in the fitness industry by sticking to a simple philosophy: build smart, durable products, listen to users, and always keep improving. Their adjustable dumbbells are known for their efficiency, compact footprint, and easy-to-use design—making them a favorite for both home gyms and high-performance training environments.

What sets PowerBlock apart is the quality of the people behind the product. Their team is made up of engineers, athletes, designers, and fitness enthusiasts who genuinely believe in helping others reach their goals. Many original team members are still on board today, bringing decades of experience and passion into every product they make.
