How long will the Spirit CT800 last?

The Spirit CT800 offers a lifetime frame, lifetime motor and deck, 10-year parts, and a 2-year labor warranty for its residential users. The motor size is rather unimpressive with only 3.0 HP yet the remainder of the treadmill is built with commercial grade parts. A legitimate heavy-set user can get quite a number of years using this treadmill depending on the level of maintenance and care taken once purchased. Keep in mind this base is not foldable!

Brief Overview

The CT800 cardio machine is a decent piece of fitness equipment and is designed with an intuitive and simple user interface that lets you choose from preprogrammed workouts. The ergonomic hand pulse sensors give users insights into their vital stats while the treadmill provides storage options for water bottles/phones and comes with built in fans.

Overall Quality

The CT800 Treadmill from Spirit Fitness is a high-performance treadmill for home or light commercial use. It features a bright white multi-window LED console, which is easy to read and simple to use while measuring resistance, calories, pulse, time, track, speed, incline, and more. Direct speed and incline buttons help keep workouts more efficient. To keep users in the 'zone' the CT800 has contact and wireless heart rate options along with two built-in cooling fans. The maintenance-free deck provides a smooth and quiet surface for all cardio needs and the durable commercial grade pre-lubricated belt is designed to handle increased usage and offers a 22" x 60" running surface. The 384 lbs. weight of this treadmill creates a sturdy, stable base for users weighing up to 450 lb. The powder coated steel frame is tough enough that it can support heavier users (remember muscle weighs TONs more than fat) without feeling too flimsy or wobbly during use meaning moderate runners should get a decent workout. The CT800 also offers larger rollers which help in smooth belt/deck operation and puts less stress on the belt.

There are so many high-end treadmills out on the market these days, it’s hard to know which one will be best for you. A lot of treadmill manufacturers want their product to stand apart from competitors but all too often, offer similar features making the selection confusing if you aren’t laser focused on exactly what you want. The CT800 has everything that most people would need and if you are not too hung up on looks, this treadmill should be a faithful companion for years.
