The Dynamic Fluid Fitness M550 is the brand's champion fluid rower for health clubs and commercial gyms. A side-mounted Twin Tank, office chair height seat and comparatively short frame make it easy to get on, quick to adjust and economical with floor space, while 10 resistance levels cover everyone from seniors to elite athletes.


Patented variable fluid technology changes resistance instantly at the turn of a lever, with 15% more resistance from the updated impeller.
An instant catch and continuous resistance, with the sight and sound of water driven through the dual tank.
The Interactive Performance Monitor shows time, speed, distance, stroke rate, calories per hour, watts and resistance level.
A heart rate receiver is fitted as standard and works with all main heart rate belts.

The higher seat makes entry and exit easy, ideal for members of every age and ability.
Concealed low-friction rollers ride on hardened, dual anodized aluminum seat rails.
Height adjustable footplates with straps keep feet secure in a comfortable rowing position.
Heavy duty wheels make it easy to reposition or store upright.
Two sealed chambers move water between a passive and an active tank, so resistance changes at the turn of a lever instead of by draining or refilling the tank like single-tank water rowers.
Pick a level and the console's auto-detect Bluetooth monitor reads it automatically, so the numbers on screen always match the setting you rowed at.
Water resistance builds smoothly through the drive with the sound of moving water, without the fan noise of air rowers or the flat feel of many magnetic rowers.
At under 77 in long, the M550 is the shortest commercial rower in the Dynamic Fluid Fitness range, while keeping a high, easy-access seat.
Choose the M550 for health clubs, high-traffic facilities and premium training spaces that need easy access and a short footprint. You will need about 124 x 79 in of operating space, or 34 x 32 in when stored upright.
