I purchased my C2 machine in April 2005. My primary purpose for rowing was weight loss. I use my C2 in combination with a treadmill and an elliptical machine. I have lost 20 lbs. by exercising and the C2 machine has helped me keep that weight off. I have recently been rowing 30 minutes a day 5–6 times a week. My 2008 goal will be to row at least 2 million meters. Thanks C2 for producing a great machine.
