Versatile, Quality Adjustable Dumbbell Set

The Universal Power-Pak 445 is a good mid-price adjustable dumbbell set for any home gym, from novices to experts. It features up to 45 pounds of weight per dumbbell, adjustable in 5-pound increments, a workout guide, and a thermoplastic rubber handle. It also comes with its own stand and an easy-to-use dial system that gives you faster adjustment times than other, more complicated adjustment methods.

Adjustable from 4 to 45 pounds

This model features a weight range of 4 to 45 pounds, making it an ideal set for someone starting out with a strength training routine or who practices either P90X or HIIT routines, both of which emphasize variety over actual weight.

5-pound increments

The Universal Power-Pak 445 features 5-pound weight increments, which is standard for adjustable dumbbells and helps you maintain steady strength training over time.

Workout guide

The Universal Power-Pak 445 comes with a workout guide with suggested routines and exercises.

Bulkier plates

The plates used with these dumbbells are bulkier than regular dumbbells. This will interfere with some lateral and chest exercises, though it is actually beneficial for your stabilizers as you have to train your muscles to accommodate for the extra space they take up during your routine.

Rubber handle

The Universal Power-Pak 445 has a thermoplastic rubber handle, not a metal handle. While some weightlifters prefer the natural feel of metal handles, some will appreciate the extra grip of the rubber handle, as well as the kinder texture which is less likely to cause callouses.


Universal stand

Many adjustable dumbbell sets have a custom stand that can be purchased independently of the dumbbells, but the Universal Power-Pak 445 includes the stand in the purchase price, making it one of the better values in its price range. The stand features two cradles for resting the dumbbells during breaks in your routine or between workouts, and speeds up the adjustment time.

Easy to use dial system

The Universal Power-Pak 445’s dial system is one of the easiest ways to adjust weights available today, as well as one of the quickest. It is very intuitive and you will not need to think about it much after a few initial uses. This helps you focus on your workout instead of on the technology.


Weights shift

The weights on the Universal Power-Pak 445 will shift as you lift them during workouts, but they are secure. This is scary to some users as the wobbling and noise can feel as though they are going to fall, but it is very unlikely. It is an unfortunate feature, because it detracts from the functionality of these dumbbells by making the user uncomfortable during his or her workout.

Overall Review

The Universal Power-Pak 445 is a great mid-range alternative to pricier adjustable dumbbell sets. It provides an adequate weight range for HIIT and P90X routines and has an intuitive dial system that allows for speedy adjustment times. While the shifting of the weights while in use is certainly a major concern, it does not imply shoddy manufacturing and you will find that these dumbbells last you for as long as more expensive models.
