I go the gym three times per week, but I wanted to have a treadmill that I could use at home as well. I asked one of the physical trainers at my gym if she had any recommendations, and she advised me to purchase this one. This treadmill is affordable and reliable. I've had it for over a year now, and I use it almost every single day. Performance The performance of the ProForm XP 580 treadmill is extraordinary. There are so many built-in workouts to do which I love. You can also select your own speed and/or incline if you choose to. This treadmill shifts smoothly and with ease to the different speeds and inclines. Comfort The handles are very comfortable to hold on to. I always have a comfortable walk or run on it. Ease of Use This machine is very straightforward and easy to use. The level indicator and start button are pretty much all you need to know how to use. Durability Like I previously stated, I use this machine almost every day, and it is still in great shape. Design I love the design of this machine. However it is on the larger side.
