If you already have workout accessories like dumbbells, kettlebells, and resistance bands or prefer to do bodyweight workouts that don't require equipment, then the Mirror may be a better option. Unlike other smart mirrors, you also have the option to select one-on-one personal training sessions. The NordicTrack Vault is a great option if you're already looking to purchase gym equipment or prefer strength training. NordicTrack, ProForm, and FreeMotion make other iFit-enabled equipment like bikes and treadmills, so the Vault is especially convenient if you own another one of these machines or plan to buy one.
