What I Like:


The Nautilus T616 comes with structural beams that support the frame to minimize vibrations and wobble underfoot. It is powered by a 3.0 HP motor that runs quiet and sits under the motor hood on the front of the deck, so you can fold the treadmill vertically. This powerful motor offers a smooth operation for the incline and speed adjustments.

This model has two handlebars on both sides of the deck. The handlebars have a coating to prevent moisture and sweat build-up. The treadmill also has a curved horizontal support bar that holds the heart rate sensors that transmit your HR to the console screen.

It has a 20″x 60″ deck that offers enough stride length for jogging. However, this may not be an ideal choice for runners who do a sprint or run long distances at a fast pace. The running deck is equipped with StrikeZone cushioning to help absorb impact and minimize joint compression and fatigue.
