Pros
  • Sturdy

  • Rust resistant

  • Non-slip handle grips

Cons
  • Adjustments take more time

This set includes 16 different weight plates to help you achieve a minimum of 5.6 pounds and a maximum of 66 pounds, depending on your fitness level and the exercise you're performing. The handles also feature non-slip grips that are both comfortable and safe for heavier lifts. The classic design does require more time when it comes to adjusting your weight resistance, so this pair is better suited to more traditional strength-training workouts.

Ease of Use: Manual weight plate adjustment | Weight Range: 5.6 to 66 pounds | Durability: Iron-plated bars and frosted weight plates

What to Look for in an Adjustable Dumbbell

Ease of Use

Adjustable dumbbells use a variety of different mechanisms to secure the weight plates to the handles, and not all of them are easy or intuitive to use. So be sure to select a pair that makes sense to you so you can swap weights quickly mid-workout and maintain the effectiveness of your training session.

Weight Range

When selecting adjustable dumbbells, it’s important to think about both the minimum and maximum weights that the set can provide. Ideally, the lower weight settings are ones you feel comfortable using now, giving you room to either maintain your current fitness or increase your muscle strength as you move toward the heavier weight settings.

Durability

Since you rely on one set of adjustable dumbbells to meet the majority of your strength-training needs, you want them to last. Consider the materials used, the type of exterior coating used, and whether the weight change mechanism allows the plates to slide around or holds them securely in place, as all of these things impact durability significantly.

FAQs

How do adjustable dumbbells work?

The goal of adjustable dumbbells is to provide a wide range of weight options in a single set, requiring only one purchase and taking up significantly less space in your home gym.

Most adjustable dumbbells utilize lever, dial, or pin mechanisms to shift the number of sliding weight plates that are attached to the dumbbell handle. This adjustment typically occurs in set increments to promote consistency in your strength training workout. The adjustment also requires minimal work on your part and takes just a few seconds, so you can focus on your actual workout and achieving the muscle strength and tone you desire.
