The Horizon Fitness T101 and The Horizon Fitness 7.4 AT Studio are both outstanding treadmills from Horizon Fitness, but they differ in several key areas. Both models offer motorized incline and Bluetooth connectivity, but the 7.4 AT Studio model comes with a more powerful 3.5 HP motor and a higher speed range up to 12 MPH, compared to the T101’s 2.5 HP motor and 10 MPH maximum speed. The 7.4 AT also features a larger belt size and a higher weight limit, suggesting a more robust build for heavier or taller runners. Additionally, the 7.4 AT treadmill includes more built-in programs, handlebar buttons, and is compatible with popular training apps such as Peloton Digital and Zwift. However, both models offer a lifetime warranty for the frame and motor, though the 7.4 AT Studio provides a longer warranty on parts and labor​.

- Handlebar Buttons: Unlike the T101, the 7.4 AT Studio treadmill includes handlebar buttons.
- Training Apps: The 7.4 AT Studio is compatible with popular training apps such as Peloton Digital and Zwift.
