A:Answer Yes. This treadmill is heavy. However, we did not find it unmanageable. I was able to assemble it and put into place with minimal assistance from my wife. Honestly, putting it together was much easier than expected.
On the plus side, this treadmill is also very sturdy. I am not sure what your fitness level is but, if you have had other treadmills, you know how important stability is - because having something slip or move while you are running is dangerous. My wife is a fitness athlete so we do a lot of "extreme" workouts (heavy inclines, sprints, etc...). So far, this has been solid as a rock.
Hope this helps.
