The Challenge AR features an advanced computer monitor providing the rower with measurable performance output, an ergonomically designed seat that rides on precision bearings and rollers for absolute smoothness, an upgraded footboard with advanced heel support, and an innovative soft grip handle to eliminate stress on the hands and wrist during the comfortable, but physical workout.
The model E’s seat stands 6 inches higher. And while the model D’s monitor rests on an adjustable arm, the E’s sits on unbending metal. These few technical differences do nothing to impact ride feel. We recommend the $200-cheaper model D as the best buy, but the Concept 2 E will appeal to anyone who values a higher seat and more solid construction.
Instead of air or hydraulic resistance, the Elite Wave Water Rowing Machine emulates actual rowing with lifelike water resistance. The paddles glide through the water housed in the reservoir, making the rowing stroke smooth from start to finish, and like rowing on a body of water, the resistance increases infinitely the faster you row. Not only does this feel like rowing on water, it sounds like water. Different stroke speeds and intensities vary water motion, resulting in realistic water resonance.
