"I am a male, aged 65, who has been diagnosed as having osteoarthritis specifically affecting L1 through L5. I have experienced difficulty with prolonged standing, running, prolonged walking, and generally have stiffness and inflexibility due to this condition. My exercise regimen precluded running, treadmills, and related forms of exercise. In January of 2008 while shopping for a recumbent cycling machine, a salesperson at Busy body recommended the WaterRower. I instantly fell in love with this machine. Have been using my WaterRower consistently since January and find that it complements by condition. There is virtually no stress on my lower back. I alternate working out on the WaterRower with riding a bicycle. The combination works well for me. I recommend the WaterRower to anyone who wants a reliable form of exercise with minimal stress. The added benefit is the relaxation induced by rowing to the sound of sloshing water."
