505 CST Features

  • Built and design

Anyone looking for long-lasting workout equipment will want to know about its design and construction. This one is built to last, thanks to a sturdy construction that is stable enough even when you are running on it. But the best part is that it comes with a foldable design.

When assembled and ready to use, it measures 74inches (l) by 94inches (w) by 154inches (h), and 37.7inches (l) by 37inches (w) by 171inches (h) when folded. Plus, it weighs around 190lbs. This machine is not a lightweight unit, which will need more than one person to carry it to the house.

But this means that it is sturdy enough to hold more weight capacity. Specifically, it has a maximum user weight of 300lbs, which is decent enough.

  • Motor

Of course, a treadmill will run on a motor, and that is why you should consider if the machine you intend to buy has a reliable motor. Well, this one comes with the Mach Z commercial-grade electromagnetic DC motor. This is powerful enough and can last for a very long time. Luckily, it runs quietly to avoid any distractions. It has a 2.5HP rating, which isn’t bad at all.

The motor spins the running belt, which offers a running area of 20 by 55 inches. We thought that was slightly narrow, but for a normal size user, it won’t be a problem.

  • Programmable Workouts

If you just got off the bed and you want to hit the treadmill, you won’t have to worry about the usability because it comes with preloaded workout programs. This way, you can easily jump on it and select your desired program. 18 preloaded programs offer you a versatile workout session. The workout programs offer something for everyone. Plus, they are developed by professional personal trainers to fit anyone’s workout goals.

  • Workout Experience

Obviously, you would want to know if the workout machine will offer you the right experience when working out. That is why you must consider the related features. In this case, you should look out for the incline and speed level of the treadmill.

The incline level is meant to simulate a steep or flat terrain. Here, you adjust it according to how intense you wish your workout to be. On the other hand, the speed is just meant to regulate your speed as you run. The higher you set it, the more you will have to increase your speed. For a beginner, it is always advised to start at a low speed as you enhance gradually.

The speed is adjustable from 0 to 10mph, while the incline can be adjusted from 0 to 10%. All these can be done at the push of a button.

There are some hand pulse grips and a Bluetooth smart wireless receiver that helps to track your heart rate.

  • User Experience

505 CST is easy to use machine, and you won’t really have a hard time. Setting it up is a walk in the park since it comes with a user manual to take you through it. But you’ll need some extra hands if you want to carry it.

There is a 5-inch backlit LCD that lets you track your progress. All the controls are accessible at the touch of a button. Plus, you can be confident of an entertainment unit that serves you accordingly. There is a compatible music port for connecting to your iPod or mp3 player. Plus, there are two 2-inch speakers and a tablet holder for extra convenience.
