The Concept 2 Model E Rower is a slight adaptation of the Model D, featuring the same PM5 Performance Monitor (with a longer arm), ergonomically designed handles, adjustable foot-rests, and efficient flywheel design. One of the key differences is the Model E's raised 20" seat height (6" above the Model D position), which can allow athletes with balance or mobility concerns to get on and off the machine with less effort. The chain housing on the Model E Rower is also fully enclosed, helping keep the nickel-plated chain clean and out of harm's way. To change how much air enters the flywheel housing on each stroke, you can adjust the machine's spiral damper to any setting from 1 to 10. When done training, you can quickly break down the rower into two segments for storage or use the included caster wheels for easy transport. While some might associate traditional rowing exercises with upper arm strength, the Concept 2 Rower actually produces one of the more comprehensive, full-body workouts of any fitness machine in the industry—developing efficient core power and leg strength without over-taxing the back.
