In-depth Review of Horizon T303 Treadmill


Horizon’s T303 is the highest treadmill of their GO Series lineup. These treadmills are designed for smaller areas and characteristic decrease charge points, making them a desirable option for many users. At the same time, you lose many updated techs and more suitable cushioning discovered on different costly machines with the T303. You get a stable treadmill that sits firmly at the ground, doesn’t rock, is straightforward to step on and off, prefers a bit as needed, and has a quiet 3.0 HP motor. This Horizon Fitness T303 Treadmill is a fantastic choice for residences, small rooms, or folks that want to wrap their treadmill in a corner while no longer in use. The T303 gives you several bangs for your buck, and we are inspired by the overall exceptional and design. A metallic frame supports the deck, which capabilities 3-Zone cushioning. The 3.0 HP motor is housed on the deck’s front, shielded using the motor hood, which protects it from foot impact. The inclined arm under the deck lifts and lowers the on foot grade so that you get extra than just flat avenue schooling. The motor is powered adequately for daily use, but we advise this machine for people who plan to stroll and jog. Heavy education or lengthy runs may tax the motor with repeated use.


Like top treadmills, the Horizon Fitness T303 Treadmill has floating handlebars that expand from the console’s front and hover over the deck’s sides. These are best for purchasing on and rancid the treadmill and provide a firm handhold when needed. However, they may be extensive enough you can stroll fingers-free and permit your arms to swing without hitting them. The handlebars are lightly lined for safety. A brief wipe down with sanitizing wipes or cloth will do away with any fingerprints or germs. The handlebars are sweat-resistant and will now not take in moisture.

There are more horizontal handlebars that span the deck’s width entirely under the console. These feature heart charge sensors on the way to transmit your HR to the console show. The horizontal bars are thinner, so you can fully grip them as wanted. When you modify metrics on the console or choose software, this front handlebar affords a pleasing region to hold the balance simultaneously as you preserve to stroll.


The Horizon Fitness T303 Treadmill proprietary 3-Zone is cushioning because this deck has special zones relying on where you step. The front zone gives a cushioned impact region simultaneously as the rear area is less attackable and lets in for a stable toe-off. Good taking walks shape makes a big difference in postural and spinal alignment. It is useful to have a strong however pliant floor underfoot to aid and cushion your stepping motion.

The 3-Zone cushioning is genuinely a step up from outside surfaces; however, this isn’t the most cushioned treadmill. It gives excellent traction and foot support, and we respect that any cushioning is better than none. But users looking for more cushioning in the deck may additionally discover the Horizon Fitness T303 Treadmill slightly underwhelming.


The deck is 60″ long, which’s well-known for folding treadmills. This Horizon Fitness T303 Treadmill is the minimum we advocate for absolutely everyone near or over 6 feet tall. The width is 20″, that’s a piece less than the 22″ we see on different folding treadmills.

Still, if you have a trendy walking gait and don’t want the more lateral space, it could now not be a problem. The 60” in length gives enough room for a light walk, strength taking walks, jogging, or the interspersed dash C programming language. While we don’t advise this for heavy training, you could sincerely run on it, and the deck will produce enough fore/aft room for a long stride.


As referred to, the 3.Zero HP motor is best for walking and ordinary walking but may not be best for lots of education. This motor functions the Johnson Drive System, which runs at lower RPM’s so the motor doesn’t overheat. Most customers will find the Horizon Fitness T303 Treadmill to be masses effective for at-home conditioning. The engine is quiet and manages speed and incline adjustments efficiently. There’s no hiccup in among settings, and also, you don’t need to keep on for balance while the rate adjustments or the deck inclines. All movement could be very fluid so that you can keep going during all motorized modifications.

The Horizon Fitness T303 Treadmill has an impressively low profile motor hood. Since folding treadmills typically house the motor on the top of the deck that allows you to fold, it can be inside the manner if you stand too close to the console or the deck’s front. However, the Horizon Fitness T303 Treadmill’s motor hood is relatively low and sits up away from the on-foot area beneath the console. We did not have any issues with our toes hitting the Horizon Fitness T303 Treadmill’s motor hood.


The Horizon Fitness T303 Treadmill has LCDs that show exercising feedback and energy, distance, coronary heart fee, incline, tempo, speed, and time. While the console offers impressive facts, it’s miles a bit cluttered and hard to navigate. This Horizon Fitness T303 Treadmill isn’t our favorite console layout. Once you figure out where the whole thing is, steering and using the console is less complicated, but there is a curve knowledge. We’d like to see a bit extra updated tech and a streamlined console with fewer buttons and icons.


The console layout includes buttons for program picks at the pinnacle proper and left of the console. There are 4 on the right and 4 on the display screen’s left. The middle display is blue backlit with huge white virtual numbers. Metric readouts for velocity, incline, energy, time, distance, etc. They are all displayed on this display screen and the modern software.

Below the primary screen are 4 more buttons at Bluetooth, Speed Up/Down, and Enter. There are Up/Down buttons for the incline on the left, one for the fan, and one to alter display alternatives. In the middle of the console, INTERVAL buttons make it clean to fast jump from one place to another while doing HIIT software. This Horizon Fitness T303 Treadmill is a unique characteristic, and even though we don’t love the console, the addition of the INTERVAL buttons may be convenient. Your washroom set your metrics for INTERVAL 1 and INTERVAL 2 with a SPLIT button within the middle. To use the INTERVAL characteristic, preserve the Interval 1 or Interval 2 key to save your preferred velocity and incline settings. When pressed, the Interval Timer robotically resets to 0 so that you can track the C language classes within your exercising. The smaller display screen shows Incline or Distance, Segment Time or Total time, and Speed.

Beneath the INTERVAL buttons, the central Start/Stop buttons and Safety Key take a seat at the console base. There is a fan between those buttons that circulates air at some stage in your workout. This Horizon Fitness T303 Treadmill isn’t the most powerful fan, but it gives a breeze chunk.

There are 8 preset buttons for velocity (2, 3, 4, 5, 6, 8, 10, 12). You locate 8 buttons for numerous Inclines (0, 1, 2, 4, 6, 8, 10, and 12). There are also the +/- buttons on principle console for different speed and C program language period settings.

Tablet Holder

There may be a wide ledge to preserve your telephone or tablet at the top of the console without blocking off the display screen. This Horizon Fitness T303 Treadmill is a pleasant addition because many media shelves partly or wholly block the screen. You can set your tool here to view a 3rd party fitness app, watch a program or maybe study or pay attention to a podcast while exercising. The intensity and function of the media shelf make it very useful.


There are two wallets on either side of the console to preserve a small water bottle, phone, keys, etc. Likewise, a large storage tray spans the deck’s width only beneath the console. This tray provides a useful extra garage because even when going for walks on a treadmill at home, it is excellent to have non-public gadgets (TV far off, e-book, and so on) close by for comfort.


The Horizon Fitness T303 Treadmill has a superior Bluetooth era to stream media thru the integrated audio system, track your coronary heart fee, and sync with various apps. There is likewise a rapid-charge USB port behind the pill holder so that you can rate your tool during its use. You also can sync your device to the treadmill to play any application or instructions right on the speakers.


The Horizon Fitness T303 Treadmill plays correctly underneath trying out and feels at ease underfoot. As referred to, the responsive motor is significant here. There is not any lag or pause between pace and incline settings. Which way, you need to be geared up! When you regulate the dial to boom speed, it responds nearly straight away, so be prepared to pick up that pace.

Incline / Decline variety

The Horizon Fitness T303 Treadmill inclines to 12%. Many folding treadmills allow a 15% max incline, so this doesn’t cross as steep as others in this fee variety. However, a 12% grade still offers you masses of schooling alternatives for hill paintings, rolling hills, incline education, etc. Working an incline has numerous benefits, including extended calorie burn and greater muscle engagement. Since it is more challenging than strolling or running on a flat street, running up a hill burns more incredible energy. It also adds different challenges while you combine diverse speeds with various inclines. The incline feature makes it so that you can work difficult but stay low-impact for a challenging exercise that burns extra energy and recruits extra of the powerhouse lower-body muscular tissues.

Eight Preloaded Routines
