Super convenient location. The facilities aren't as nice as some other downtown locations but it's great for a quick workout at lunch or after work. It does get a little busy during the after work rush though.
If you want to take classes here, the group fitness room is quite large and can accommodate more than some other Goodlifes nearby. Their spin classes are held in a separate room that is located upstairs right beside the UP Express, definitely ask for directions if it's your first time.
