Why this model.
The Dynamic Fluid M550 is the flagship rower in the Dynamic Fluid lineup, combining 10 levels of adjustable fluid resistance with an office-chair-height contoured seat for the ultimate in accessibility and comfort. The updated impeller design delivers 15% greater resistance than previous models.
Office-Chair Height Seating
The M550's seat sits at office-chair height, making it the easiest rower to get on and off — a critical feature for rehabilitation facilities, older users, and anyone who values accessibility. Despite this elevated position, the rowing biomechanics remain optimal with a smooth, natural stroke path.
10-Level Fluid Resistance
The patented twin tank system with adjustable fluid resistance provides a massive range from gentle rehabilitation recovery to high-intensity athletic training. The Bluetooth Auto-Adjust Monitor with IPM tracks every metric: time, speed, distance, stroke rate, calories per hour, and watts with precision accuracy.
Compact and Mobile
At 76.8" long, the M550 features one of the most compact footprints in its class. Transport wheels and vertical storage (just 33.9" x 31.9" upright) make it ideal for spaces where equipment needs to be stored between sessions. Built with premium steel and aluminum for a 330 lb user weight capacity.
