PowerBlock revolutionized the fitness industry in 1993 with the launch of the world’s first commercially successful adjustable dumbbell. Our patented, selectorized design transformed how people train at home—replacing entire racks of traditional dumbbells with one compact, efficient solution. It also transformed the world of pro sports by becoming commercially available to hundreds of professional sports teams, redefining how athletes train, recover, and optimize performance.

For over 30 years, we've led the way in innovation, setting the standard that many others have tried to follow. From unmatched durability and expandability to space-saving engineering, PowerBlock continues to raise the bar in strength training equipment.

We don’t just build adjustable dumbbells. We invented them, and here's how we make sure to continuously stand out:

PowerBlock dumbbells feature a patented selector pin system that functions like the adjustable weight stacks found on gym machines—allowing you to quickly and easily choose your desired weight by sliding a magnetic pin into place. This design makes weight changes fast, smooth, and secure, so you can focus on your workout without interruption.

Micro weights allow you to fine-tune your resistance in precise 2.5 lb increments, making them perfect for micro-loading. This level of customization supports gradual strength gains and helps optimize progressive training programs for maximum results.

PowerBlock adjustable dumbbells are designed to grow with you. Starting with a compact base set, you can easily add expansion kits to increase your weight range—giving you a complete, all-in-one-dumbbell solution that adapts as your strength improves.

Expand your training possibilities by attaching compatible accessories such as the straight bar, EZ curl bar, and kettlebell handles—adding versatility and variety to your workouts without needing additional equipment.
