Patented Fluid Innovation Technology the secret behind variable water resistance rowing.

First Degree Fitness water resistance rowing machines use a unique patented twin tank system which facilitates the transfer of water to and from a passive holding tank, to an active tank where variable amounts of water can be turned by a multi-bladed impeller.

FDF indoor water rowers feature a twin chamber tank, allowing the transfer of water at the turn of a dial, creating rowing machine resistance levels from feather light to Olympic sprint. This is what we call variable fluid resistance.

The combination of a multi-bladed impeller and internal baffles within the rowing machine water tank, generates a smooth uniform stroke unrivalled in its precise replication, including no lag of resistance at the catch, and continued resistance all the way to the finish, just like in a boat. This is why FDF indoor rowers allow the rider to maintain a proper boat rowing technique.

Other water resistance or air resistance indoor rowers deliver a force curve where the resistance falls off during the second half of the stroke, well below that experienced at similar paddling rates in an on-the-water rowing boat.
