Adjustable dumbbells have become an essential part of every home gym, especially for those focused on efficient strength training without sacrificing space. Within the first few workouts, it’s clear this product offers the solid feel and flexibility needed for consistent progress.
Whether you’re a beginner interested in muscle building or a seasoned athlete looking for a reliable free weights option, the Cap Barbell Adjustable Dumbbell Weight Set stands out. The all-in-one design saves space and lets you switch up weights quickly—perfect for circuit routines or isolated dumbbell workouts.
This model is crafted with coated cast iron plates, offering lasting durability and a professional look.
Key Features of the Adjustable Dumbbells
- All-in-One Adjustable Weight Set: This set includes two 17” handles, four 1.25 lb plates, four 2.5 lb plates, sixteen 5 lb plates, and four star-lock collars to target different muscle groups or support full-body routines. Switching between weights for various exercises is seamless.
- Premium Cast Iron and Epoxy Finish: Built from high-grade cast iron and covered with a black epoxy layer, these plates resist rust and wear, ensuring they last through years of intense dumbbell workouts.
- Diamond Knurled Chrome Handles: Medium-depth knurling on chrome handles ensures a secure, non-slip grip during high-rep muscle building sessions.
- Secure Star-Lock Collars: The star-lock collar design features rubber O-rings for fast plate changes and keeps weights stable during rapid exercise transitions.
- Compact Storage: The streamlined, stackable design makes it easy to store these free weights neatly in any space-limited garage or apartment gym.
Real-World Performance Testing
The Cap Barbell set delivers excellent versatility for everyday strength training needs. In our performance reviews, we tested the adjustable dumbbells across pressing, curling, row, and fly movements. The handles are comfortable with just the right amount of chrome knurl, providing good control even during sweaty sessions.
Testers noticed plate changes were fast, thanks to the star-lock collars. With a combined max load of 105 lbs, the set easily supports progressive overload for intermediate lifters in a home gym setup. The compact storage solution is perfect for keeping your area uncluttered.
However, note that the set’s plates only fit 1-1/8” handles, so mixing with standard size weights isn’t possible. For beginners, the total weight is more than enough, but advanced lifters seeking heavier loads may outgrow this faster than a larger system. The tough epoxy finish has held up after repeated drops—a testament to its long-term build quality.

How It Compares to Alternatives
Compared to leading competitors like Bowflex SelectTech 552 and Yes4All Adjustable Cast Iron weights, the Cap Barbell set shines in build quality and value for the price. While Bowflex is faster for on-the-fly weight switches, this model’s robust cast iron plates and reliable star-lock collars give it an edge for long-term use.
This product is more affordable than other premium options but offers a similar home gym experience. Warranty coverage is basic, which is in line with the category. In terms of compact storage and classic design, the Cap Barbell model appeals to users wanting simplicity and durability.
Who Should Buy This Product?
This tool is perfect for three main groups: beginners building their first strength training setup, intermediate lifters upgrading free weights, and anyone looking for a space-saving adjustable weight set for a home gym. The robust construction and easy storage make it a good match for small apartments, home offices, or garage gyms.
Advanced athletes seeking extremely heavy loads or those wanting instant weight changes for high-intensity supersets may want to opt for selectorized models instead. If portability or ultra-fast adjustment is your priority, you might consider modern alternatives.
