Horizon Fitness 7.8 AT Treadmill – practical with silent motor

Introducing the Horizon 7.8 AT: Your Ultimate Treadmill for HIIT Training. Here’s why this treadmill stands out as a HIIT powerhouse:

Effortless Interval Training: Jumping into interval workouts has never been simpler. The console is equipped with Sprint 8 training programs, featuring high-intensity intervals interspersed with varying recovery levels from easy (level 1) to intense (level 20). Automated speed and interval adjustments take the guesswork out – just focus on your run, and the machine adapts for you. No buttons to press, just your fitness goals to conquer.

Unlock the Benefits of Interval Training: Interval training is backed by science. It elevates your oxygen efficiency (VO2 Max), enhances insulin sensitivity, torches calories in less time than steady-state cardio, amplifies fat burn, and boosts heart health. Plus, shorter but intense HIIT sessions fit snugly into your schedule, allowing you to seize the day sooner.

Powerful Motor and Streamlined Design: With a robust 4.0 horsepower motor, the Horizon Fitness 7.8 AT Treadmill provides a swift and satisfying workout. Its low step-up height ensures effortless on and off, while its hushed operation sets it apart from comparable treadmills. The motor’s rapid adjustment capability keeps your pace in check. No wait, just action.

A robust 4.0HP motor ensures seamless adjustments in speed and incline, catering to users across various fitness levels. The Horizon 7.8 AT accommodates a range of preferences, making it suitable for easy-paced walkers who seek simplicity and straightforward programs. It equally caters to runners and joggers committed to consistent training. However, where it truly shines is in its HIIT training capabilities. The preloaded Sprint 8 programs, comprising 20-minute intervals of high-intensity training, effectively elevate heart rates and amplify calorie burn. This machine is tailor-made for those dedicated to regular HIIT sessions, particularly enthusiasts of the Sprint 8 program.

Horizon proudly asserts that the 7.8 AT’s motor boasts a 33% quicker response rate compared to its treadmill counterparts. In my experience, I found the adjustment dials to be swift in altering the displayed speed, whether upward or downward. Yet, I did not distinctly observe the responsiveness to be significantly faster compared to other treadmills like the Nordictrack 1750, ProForm 5000, or Sole F80. It’s important to note that, during running, there’s an inherent safety limit to how rapidly the belt can accelerate. While the 7.8 AT felt adequately responsive for my needs, the perceived 33% speed advantage was not quite discernible in my experience.

At a stationary pace of 3.0mph with no user walking, our decibel meter registered a reading of 63 decibels on the Horizon 7.8 AT treadmill. With someone walking at 3mph, the decibel levels increased to approximately 68. When the treadmill was set to a running pace of 6mph, the noise level peaked at 78 decibels.

In contrast, the Nordictrack 2450 exhibited a baseline noise level of 68 decibels at 3mph (without a user walking). This figure escalated to 72 decibels when a person walked at 3mph. Running at a pace of 6mph on the Nordictrack 2450 generated a noise level of 82 decibels.

Evidently, the Horizon 7.8 AT is notably quieter, particularly at lower speeds. As one accelerates to faster speeds, and especially when accommodating heavier users, the treadmill produces more noise. This observation holds true for treadmills across the board, as noise tends to escalate with heightened activity and user weight.

Your Control, Your Way: The console is tech-savvy without the fuss. It lacks a touchscreen or subscription burden. Instead, it features two tablet shelves, inviting you to integrate your phone or tablet with third-party apps or perhaps indulge in a Netflix binge while you run. Horizon lets you lead your training without barriers.

Seamless App Integration: Horizon’s innovative edge shines through. While the console might not boast futuristic tech, it champions freedom. No video-loading waits or mandatory subscriptions. The 7.8 AT syncs seamlessly with third-party apps. Be it Zwift, Peloton, or the AFG App, you’re in control, crafting your fitness journey.
