The Nautilus home treadmill product line for includes two models: the T514 and the T516. Both treadmills are good quality machines, but when reviewing the T516 it had a number of upgrades and is more suitable for serious runners. Although the Nautilus T516’s MSRP is about $2500, the machine has been discounted by up to $900.

What We Like

  • Stability: Nautilus home treadmills are known for being strong and sturdy. The T516 is foldable but supports users weighing up to 350 pounds.
  • Motor: The T516 has a powerful 3.2 HP continuous duty motor. This can easily support a runner’s daily training. Users can reach a top speed of 15 mph.
  • Track: Nautilus’s patented Softrak suspension deck reduces the impact to users’ joints and has received excellent customer reviews. The 58” track is long enough for most users.
  • Incline: The T516 offers a 15% incline, which is significantly greater than the typical home treadmill incline of 10%.
  • Console and programs: The Nautilus T516 is loaded with 26 workout programs. These include 4 heart rate programs, which are used in conjunction with an included grip monitor, and 9 time/distance programs. The console can save four user profiles. Progress is monitored with backlit LCD windows.
  • Compactness: Nautilus machines are best for homes with plenty of workout space; the T516’s footprint is 78”x32”. However, the machine does take up less space when SoftDrop folding technology is used.

What We Don’t Like

  • Warranty: The T516 has a somewhat discouraging warranty package. The treadmill is sold with a decent 15 year warranty on the motor and frame, but electronics are only covered for two years. Some parts are only covered for 90 days.

Our Verdict

The Nautilus T516 includes a number of upgrades over the T514, such as a longer track, more programs, and a greater incline. This model’s excellent suspension provides a comfortable workout, and the treadmill’s 26 built-in workout programs provide a lot of variety.

One cause for concern is the relatively skimpy warranty package; 90 days on wear parts is discouraging. Prospective customers should also note that the treadmill may be difficult to transport; it’s heavy and is wider than most home doorways.
