registers your speed by every footfall and recalibrates the belt velocity up to 710 times per second. This patented technology reduces joint discomfort and complements your natural running stride.

The revolutionary treadmill deck is designed to absorb the impact when your foot hits the front of the belt and added rigidity at the back of the belt for a firm push off. This patented design helps to reduce joint stress and minimize fatigue.

When training for a race, you want to be prepared to tackle all that comes at you.  With this treadmill you can train for both the ups and downs by adapting your training runs with a 2% decline and up to a 15% incline.

Built in the USA, the 400 Line of treadmills has an exceptional warranty backed by the service that gyms, hotels, universities, and military installations across the globe have come to expect.
