The World’s Best Adjustable Dumbbell

Power Blocks are the heaviest, most compact, and easiest to use adjustable dumbbells ever made. This versatile product can replace an entire rack of fixed-weight dumbbells, and requires only 3 square feet of floor space!

For weight training, nothing beats dumbbells, and this is the best adjustable dumbbell ever made. It makes it easy to quickly switch weights, which is necessary when you’re getting in a fast workout or training with a partner. And, unlike other adjustable dumbbells, Power Blocks feel well-balanced and rock solid, with no loose parts or annoying wobble. Every part of this product is well made. If you’re setting up a home gym, this is the very first training tool that you should invest in.

Why Power Blocks are Better than Ordinary Dumbbells

There are two basic types of dumbbells — fixed-weight and adjustable-weight. Fixed-weight dumbbells are the type that you find in commercial gyms. They’re compact and durable, but each one provides only a single weight. To accommodate the needs of different exercises, it’s necessary to have fixed-weight dumbbells of many different sizes. Sets of fixed-weight dumbbells are typically arranged in long racks, use up a considerable amount of floor space, and can cost several thousand dollars.

Adjustable-weight dumbbells allow their weights to be changed through the addition or removal of individual weight plates. This reduces the dumbbell set’s total cost and space requirements, but often introduces new problems. For example, most conventional adjustable-weight dumbbells suffer from one or more of the following limitations:

Slow to Adjust

Many adjustable-weight dumbbells cannot be changed quickly. Some even require the use of separate wrenches or special tools to make the adjustment. This slows down your workout, and quickly reduces the dumbbells’ benefit.

Quick to Loosen

Most adjustable-weight dumbbells hold their weights in place with some type of locking collar. These collars often do not hold the weight plates tightly together. The result is a loose weight assembly that feels awkward and unbalanced in your hand. Sometimes these collars break loose, creating a safety hazard. Other times, the collars lock so tightly that they’re nearly impossible to disassemble.

Large and Cumbersome

Most adjustable weight dumbbells have a center shaft that extends far enough to accommodate several additional weight plates and the locking collar. However, this extended shaft makes the dumbbell larger than is desirable, and can interfere with the performance of many exercises.

Power Block is the only dumbbell without ANY of these limitations. Power Block’s weight can be adjusted in seconds, without tools. Power Block’s adjustment is always safe and secure. And Power Block is even more compact than most commercial dumbbells.
