One of the USPs of Precor treadmills is the maintenance-free tread belt. The belt is infused with dry silicone and does not require lubrication on a regular basis like regular tread belts. This feature is a real time-saver. At 22”, the belt is also two inches wider than normal tread belts, which offers you more space to jog or run comfortably.

The deck is reversible. You can simply flip it over and use it. This again is a very good feature which ensures even usage on both sides and increases the lifespan of the deck.

The 425 features the highly innovative Ground Effects Impact Control system, which reduces the strain on your joints considerably. The deck has a number of shock absorbers at the front end to reduce the amount of stress on your joints. The back end is more rigid to offer you a solid platform to push off from. The deck is ideal for joggers and runners and also for those with joint and back problems.

This is yet another great feature from Precor to reduce the strain on your joints while you jog or run. The patented Integrated Footplant Technology adjusts the belt speed automatically to match your jogging or running speed. The belt slows down when you do and picks up pace when you run faster. The technology works in tandem with the cushioning system to ensure your joints do not take a pounding after each training session.

The TRM 425 can incline up to 15% and decline down to 2%. The decline feature is not available in the Energy Series machines and is a welcome addition. You can simulate running up and down a hill, which is a terrific workout to lose weight, develop cardio, and tone the muscles in your lower body.

The treadmill has touch sensors that monitor your heart rate during training. It also has a wireless heart rate transmitter. So, if you have a chest strap, you can use it as well. The SmartRate display shows you the heart rate zone you are in. It makes it easier for you to stay in the right heart rate zone and achieve your fitness goals faster.

The console is neatly designed and easy to use. It displays 13 workout metrics and allows you to store two different user profiles. You can use the tap style dome keys to adjust speed and incline instantly.

The console has a tablet holder, where you can attach your tablet and watch your favorite songs and movies. It also has onboard volume controls for iPod, iPhone, and Android devices.

The TRM 425 has a solid, stable base. There are two base levelers at the back end of the machine, which keep the deck stable during intense workouts. It also has full length handlebars that you can hold on to while training.

There is a safety key, one end of which can be attached to your clothing and the other end can be attached to the console. In case you fall or faint while working out, the key will detach from the console and the belt will stop immediately.

The console can also be password protected, which is an excellent safety feature. The treadmill cannot be operated unless you key in the right sequence. So, you do not have to worry about the kids in the household accidentally operating the machine.
