At 250lbs, you may find the City L6 or Echelon Stride to have limited cushioning and deck space. The Sole F63 is still a good budget option and folds up to reduce floor space when you're finished. Sole is consistently one of our top recommended brands due to their structural integrity and quality build. They don't have many of the bells and whistles of Nordictrack treadmills, but they last forever. If you have the budget and space for it, check out the F63 or F80 - either would be a great option!
