What are Smart Weights?
A smart weight is a dumbbell that can connect to the internet, and interact with its user through an app. [1]. They are available as fixed weights and adjustable weights. The development of those weights is still in its infancy.
Fixed Smart Weights
Mirror Ankle Weights & Weights
The most advanced smart fixed weights are the dumbbells and ankle weights that come optionally with the smart fitness mirror “Mirror” by Lululemon.
These dumbbells and ankle weights are fixed, so you need different pairs. They connect to the Mirror, track your reps and provide form correction. You also get weight recommendations for each workout.
The dumbbells are available in 1, 3, 5, 10, 15, 20, 25, 30, and 35 lbs. The ankle weights are available in 1, and 2 lbs. The dumbbells have a fixed weight, so you need several pairs.

Move It Beat
Move It Beat are light weights up to 2.2 lbs for cardio workouts. The weights are fixed, so you need different pairs for different workouts. The dumbbells support motion tracking when connected to the Move It app.
Adjustable Smart Weights
NordicTrack iSelect Adjustable Dumbbells
Adjustable weights are a single pair of weights that can be adjusted to be heavier or lighter. Most are not “smart”. They don’t connect and you have to change weights by hand with a knob or pin.
But NordicTrack iSelect Adjustable Dumbbells are an exeception. These weights are voice controlled through Amazon Alexa.
You can ask Alexa to set a specific weight and increase or decrease weight. You can also create presets for common dumbbell moves, like biceps curl, triceps extension, chest press and more.
The dumbbells have an embedded accelerometer.
The NordicTrack dumbbells work with a subscription to the iFit App. This app displays the current selected weight, remembers your weight for different exercises, and has a ton of workouts. Not only for weight training, but also for smart stationary bikes, treadmills and more.
Move It – Smart Adjustable Dumbbell
These adjustable dumbbells connect to a proprietary Move It app for motion tracking and workouts. That is why they are considered smart. However, they are not smart with regards to weight selection, this is done by hand through a handle. This Move It App is less developed than iFit.
