The benefit of adjustable dumbbells is that you can increase or lower the weight depending on your workout plan. It may even be used by multiple users as each person can get their preferred load. The NordicTrack iSelect took it a step further by integrating the dumbbells with Alexa.

The dumbbells come with an adjustable weight between 5-50 lbs (2-20 kg). You don’t need to install the weight manually as the system utilizes a motorized weight selector that responds to vocal commands via Alexa.

The whole package is a lot more compact when compared to a dumbbell set with dozens of individual dumbbells. Instead of changing the weight manually, you can focus on your exercise to get the most of it.
