Core Training Exercises Achieved with The Fluid Power Zone ERG! 

Fluid Power ERG is a heavy-duty, commercial quality ski ergometer designed to withstand high intensity, powerful workouts for your core, arms and back.

It also delivers silky smooth resistance suitable for warm-ups and rehabilitation. The unique constant load of the ERG is delivered via the semi isokinetic properties of our patented Twin Tank 10x Adjustable Fluid Resistance system. 

The load is instantly available from the very top of the action and consistent to the end, even at explosive HIIT workout speeds.

The ERG allows for bilateral and unilateral arm movements. Switching between the two is seamless, adding greater variety and challenges to any training zone. The ERG is a perfect inclusion for any type of fitness facility as a stand-alone machine or in combination with one or all of the Fluid Power Zone machines.

How Does Fluid Power ERG Work? 


At the core of all Fluid Power Zone machines by FDF is the patented Twin Tank technology, providing 10 distinct levels of Fluid Resistance. The patented technology comprises Twin Tanks, the inner passive or holding tank and the outer active or resistance tank.

When you select a high level, water will flow from the passive holding tank to the active resistance tank as you begin to exercise, and you will experience the smooth fluid resistance, no matter what your speed.

Conversely, if you select a low level, the water will be transferred away from the active resistance tank and back into the passive holding tank, lowering the resistance. You can even make adjustments on the fly to find a load that is just right for your fitness training zone.

How Vertical Twin Tanks Work


The water in active resistance tank acts as a brake to hold back the multi-bladed impeller, the more water in the active resistance tank the greater the braking effect.

The water in the active tank isn’t all staying in the active tank during the exercise (at any level), some of it is always being cycled through the passive holding tank.

As you attempt to generate more power by increasing your speed the water cycles faster between the Twin Tanks at greater and greater speed to maintain a consistent amount of water in both tanks. This creates such a unique smooth action and at virtually any speed.

Air resistance works in a similar way, however the variation in load that is possible by restricting an impeller from “no air to total air” does not create distinctly different levels of resistance, this is very obvious at low speeds.

At high speeds the two mediums, water and air, start to feel similar except for one very key difference that makes adjustable fluid resistance so unique. When the drive phase of an activity is followed by a recovery phase, as in rowing or ski ergometer exercises, during this recovery phase air does not provide the braking force that the water in our vertical tank does.

At the catch or beginning of the next drive phase the air machine impeller has high momentum and that creates a soft or no load pick up.

Essentially the resistance on an air machine cannot be felt again until your speed catches up to the flywheel and you start to apply a greater force against which the air will resist.

These differences are so easy for you to test for yourself. Compare the ROW against any common air resisted rowing machine. You will quickly see why our patented Twin Tank Fluid Resistance system is so smooth and consistent at virtually any speed.

Reasons to Include the FDF Fluid Power ERG In Your Facility

Fluid Power Zone machines are manufactured by FDF to exacting standards suitable for intense commercial fitness environments. Each Fluid Power Zone machine is designed to withstand the most vigorous HIIT workout or provide silky smooth resistance suitable for all sports, warm ups, cool downs and rehabilitation exercises.

The case for the inclusion of Fluid Power Zone in any commercial application is extremely strong.

Various pages with-in this Website outline the uniqueness of how our resistance system works and how that translates to a myriad of advantages and exercise options for different population demographics.
