NordicTrack builds connected home-fitness equipment, with a long cardio legacy centered on treadmills and an iFIT system that synchronizes machines with trainer-led workouts. Its newer Ultra line extends that approach into Pilates, including reformers with enclosed spring systems, built-in touchscreens, and real-time performance tracking. The company says its treadmills include models capable of a 40% incline and identifies itself as the official treadmill of the Boston Marathon.
