I took a star because it comes in pieces detaché no clear explanatory notice when I ordered a similar to my father in another brand that is only 3 parts to assemble. I removed another star for comfort, if you regularly use the station at the elbows, knees and hands. For the rest it is really efficasse and uses all the body. we can calculate its progress thanks to the electronic box and can increase the difficulty ... it is well worth the sacrifice of the first 2 points
