This is a professional grade commercial treadmill designed and used primarily in commercial gyms. It has the features you would expect from the highest end treadmill. It offers 27 different types of workouts,
it has a four horsepower motor that includes power factor correction. Speed range from 5 to 60 mph and elevation from 0 to 15% incline, and even up to 3% decline. It has an integrated reading rack accessories holder audio interface with external audio and visual consoles. It is designed to be extremely durable while providing Optimal Performance for gym patrons. This is the most well-appointed treadmill that Precor has to offer. This is what the pros install in their high-end fitness centers. It has Superior shock absorption that supports a solid and controlled push off at the back of the treadmill and the softer, low impact landing at the front of the belt where the highest impact takes place. This is done using a patented ground effects impact control system. This unit has technology that calibrates the belt speed up to 710 times per second based on your foot plant pressure. You will not find a smoother, or fluid, and rhythmic running experience. This unit retails for about $10,000 new. It is in perfect working order. It can handle Runners up to 400 lb. It has both vertical and horizontal impact absorption. It has a "no maintenance" running platform. It supports connection to Apple watches and includes a mobile device charger. Unlike most other treadmills, all Precor treadmill decks required no additional periodic lubrication. This is the very best treadmill you can get, IMHO.
