Perhaps the most important feature of the Concept2 Rowing Machine is the company that stands behind it. Concept2's commitment to customer service is outstanding, so when you purchase a Concept2 Rowing Machine, you get a lot more than just an exercise machine. Concept2 provides training information called "The Update" - Concept2's twice yearly newsletter that includes motivational games, Million Meter Clubs, competitive racing opportunities, online logbooks, rankings and forums and an international community of fellow rowers. Publications are included as part of your purchase of a Concept2 Rowing Machine.
