Horizon T303 - Best Features

Larger Running Surface

One of the unique features of the Horizon treadmills, even the more affordable ones, is the generous size of the running deck. Just like on the mid-range T202, you get a 20″ x 60″ belt, which is long enough and wide enough for even the tallest users.

Users of all sizes can stretch out for a jog or run, as opposed to the tight space feeling you often get on lower priced treadmills.

It also has the company’s 3 zone cushioning system, which gives you the ideal amount of support and give at each point of your stride. This helps you avoid discomfort, which typically allows you to train for a longer period of time.

Good Incline Capability

The Horizon T303 gives you up to 12% incline capability, which is great if you want to challenge yourself a little. The higher the incline, the harder the workout and the more you’ll reap the cardio benefits of treadmill training.

The T303 comes with Bluetooth capability, which allows you to use the free Pro app to control the treadmill using your phone or tablet. You can also keep track of your workout stats and sync your results with fitness apps like Fitbit and Under Armour, which is a very cool feature.

If you have a wireless chest strap, you can use that as well via Bluetooth to accurately measure your heart rate. It typically gives you a better measurement than grip heart rate measuring.

Nice Workout Variety

You get about 8 diverse built-in workout to choose from, a few more than on the entry level T101 treadmill.

This includes fat burn, hill climb, 5K, distance, heart rate, calorie and interval programs, so there’s plenty to choose from to make your workouts more interesting.

Of course, you can always choose manual mode and pick your own incline, but it’s nice to try different programs out as you just might find something that really appeals to you.

Other Great Features

On top of all of the great features above, the T303 treadmill comes with a powerful yet quiet 3.0 CHP motor, FeatherLight easy folding capability, speed up to 12 mph, Bluetooth speakers, an, multi position tablet holder, accessory tray and Energy Saver Mode, among other extras that make it a good choice.
