I am selling a lightly used Life Span Fitness under-desk treadmill (model TR800-DT3). I purchased it a year ago following an injury. It currently retails for $599. Willing to sell for $400 or consider a reasonable offer. It has wheels on one end and can be moved easily, but a truck may be helpful. It is currenly located in my office on campus. Call or text for more information: 520-235-1349.
