At the most basic level, smart strength training equipment offers greater convenience, interactivity, and guidance than, say, a basic set of dumbbells. These machines connect to the internet, and most have a screen on which you can stream workouts (though more affordable options rely on your TV or phone for that functionality). Many offer large on-demand libraries of guided classes with knowledgeable instructors, as well as customized workouts and programs based on your goals and fitness level. If you're interested in getting into a weight lifting routine but you're not sure where to start, the Tonal, or its main competitor, the Tempo Studio, can guide you.  The Tonal uses artificial intelligence to set the weights for you in each mode, track your reps and progress in real time, and adapt its recommendations as you get stronger so you always face a challenge. The Tempo Studio works similarly, using a combination of 3D sensors and AI to suggest the appropriate weight to load onto your barbell or dumbbells for each move, count your reps, and offer real-time feedback about your form to keep you honest and safe.  Some smart strength training machines even feature live classes with fun social features, like the ability to virtually cheer other users on, so you feel like you're not working out alone. Tempo, for example, adds a bit of friendly competition to its workouts with in-class leaderboards that rank participants based on the total volume you lift and the reps you complete.
