Matt Greenemeier - Dallas, Texas
”The Ultra 1 blew me away the moment I saw it, and using it has exceeded every expectation. It's sleek, simple to use, and incredibly functional. I actually look forward to my runs now, especially with my favorite iFIT instructors. This treadmill feels like the best of the best every time I step on it.”

Shawn R
"It really was pretty when I walked up to it. I haven't seen anything like it. It was very smooth and the deck was very soft. I didn't know what to expect, but it was truly a first class experience. I really liked the golf walks and the walks in Scotland."
Jeremy M
"I wasn't sure what to expect when I first got on it. It was so beautiful and architectural. I wasn't sure what I was getting into. The speed up and down lever system where you push and pull to increase or decrease your incline and speed was remarkable. I had never done that before, and the fact that the controls were on screen as well. Made it a really fun time. I really like the fans."
Michael Y
"I went for a run with Hannah Eden. She's one of the trainers on screen, and it was really neat because I felt she was there running with me and with her control of the unit via the screen, I didn't have to do anything, but really enjoyed where I was. I had a fantastic time."
