Power cord can easily be damaged More than 500 years after Leonardo da Vinci depicted his idea of the perfectly proportioned human body, a new smart strength training machine aims to help you achieve just that. The $2,200 Vitruvian V-Form Trainer is an app-connected workout platform with two cables on top that together offer up to 400 pounds of electromagnetic resistance. It allows you to perform 100-plus moves to work your upper body, lower body, and core. The machine is easy to set up and quickly connects with its companion app, which offers a small but growing selection of trainer-led classes, lets you create your own workouts, and tracks your progress.
