Pro 100 EXP

The Pro 100 EXP is designed to be the last dumbbell you'll ever need. Perfect for advanced lifters, this adjustable dumbbell can expand up to 100 lbs with the addition of expansion stages (Stages 2-4). Start with the base dumbbells and increase weight in 2.5 lb to 5 lb increments, thanks to the included micro weights. Whether you are looking to build strength while maintaining proper form or engage in micro-loading, the Pro 100 EXP is your go-to tool for progressive training. Optimized for compactness, this system reduces the space needed for multiple traditional dumbbells. The magnetic selector pin allows for quick weight changes, so you can transition between exercises with ease.

What is a Adjustable Dumbbell?

What adjustable dumbbells are

Adjustable dumbbells replace a whole rack of fixed dumbbells with one pair whose weight you change via a dial, pin, or selector plate. They are the space-and-money saver for home gyms: a single set can span roughly 5–50+ lb per hand. The trade-offs are bulkier handles, a fixed max weight, and a mechanism that can wear or rattle.

What to look for

Fast adjustment (dial or lever beats stacking plates), a wide and useful weight range, a balanced feel that doesn’t clunk mid-rep, and a durable locking mechanism. Many sets include or offer a stand — worth it, since the blocks are awkward to load off the floor.
