Am. 76 yet old female . Been in good shape and active. Developed a “ cranky” knee that no longer allowed me to use the treadmill and was looking for something with a good overall workout to keep in relatively good shape so I could continue my love of hiking and backpacking. I did my research and talked to a therapist friend which let me to looking at rowing machines, and then this make and model. The other user reviews sealed the deal. I am very very happy with this rower. Easy to set up, can be stored up against the wall if necessary but I leave it out. It comes with good instructions and user recommendations for beginners like me. Also has video on proper use. I love this machine, I get a full body, strength ing and cardiac workout with no stress on my joints. The action is smooth, it’s quiet, easily adjus adjustable for intensity and resistance. Dry very happy with my choice. Thank you to the other reviewers for their input.
