Provided by DKN Technology, the R400 is the new benchmark in Home Standard Rowing Machines. Constructed from the highest grade components it is a fantastically durable piece of equipment which requires the very minimum of maintenance. For those who want to target upper body, arms, legs, and abdominals, rowing is a great option to consider: Not only is this the most safest way of working out, but it also represents a natural fluent exercise motion, without any negative impact, neither on joints nor muscles. DKN set the natural rowing movement as its target when developing the R-400. And to achieve this they applied a double resistance system, combining an airfan with a magnetic resistance, connected to a 30 lbs flywheel.
