A 2.75 HP Mach Z motor powers this treadmill, that also allows for weights up to 300 pounds. The folding frame design uses the patented SpaceSaver design, and the deck is equipped with ProForm’s ProShox Cushioning System for joint support and comfort.
This is a compact model, weighing just 155 pounds, also has a fairly compact running area at 50 inches long and 18 inches wide (the average width is somewhere are 20″). Users can run or walk at speeds from 0 to 10 mph, and the incline range goes to 10% as well. To make changes to the speed or incline, you can use the up and down arrow keys or the Quick Incline and Quick Speed keys on the console.
Also on the console is a 5″ LCD black and white display screen that will give you the basics like time, distance, and calories burned. This model offers 16 built-in workout programs. There are also audio features like a smartphone compatible audio port and two 2″ speakers. To monitor hear rate, there are dual-grip EKG heart rate sensors. Other basics include a CoolAire cooling fan and two oversized cup holders.
The warranty on this model includes 5 years on the frame and motor, and 90 days on parts and labor.
What We Like:
- Program Variety: 16 workout programs isn’t bad on a model well under $1,000. This feature allows for greater variety overall and helps you to achieve fitness goals, whether it’s just to get into shape or drop a few pounds. This model also has heart rate programs so you can really personalize your workouts.
- Folding Design: As with other inexpensive, lightweight and compact models by ProForm, this treadmill is equipped with a folding frame that uses the patented SpaceSaver design. This model isn’t too bulky either, so it folds away pretty easily and out of the way
- Price: This treadmill is really very affordable for just $500, or less by some retailers. You won’t get a lot of bells whistles with the ZT4, but the price is hard to beat.
What We Don’t Like:
- Display Screen: This is one of the smallest, and most difficult to read display screens that ProForm makes. The black and white display also provides just the basics, so if you want more information readouts, this model’s display set up is not for you.
- Weight Capacity: This model can withstand weights of up to 300 pounds, which isn’t too good. We like to see capacities somewhere up to 400 pounds so that more people can comfortably use the treadmill. Even if only one person plans to use the treadmill, a low weight capacity can point to a tread belt that lacks durability and longevity.
The ProForm ZT4 is an entry-level model that is intended for walking, or light jogging. It’s not a high-performance treadmill and lacks in a a few areas, specifically the console and speed/incline options. For these reasons, we would recommend that if you want a treadmill intended for walking, that is still pretty affordable like this model, check out our reviews of the best buy treadmills for walkers.
