Dynamic Fluid Fitness S660 Forge Rower

Build strength, endurance, and cardiovascular fitness with the Dynamic Fluid Fitness S660 Forge Rower, a full-commercial rowing machine engineered for demanding training environments and serious home fitness.

The S660 Forge combines Dynamic Fluid Fitness's Variable Fluid Resistance technology with a precision-aligned twin-tank system and updated impeller design that delivers approximately 15% greater resistance than previous designs.

Five Fluid Force resistance levels let you adjust the intensity and feel of your stroke, while the advanced Bluetooth Auto-Adjust Interactive Performance Monitor automatically recognizes the selected resistance level and adjusts performance calculations accordingly.

An elevated contoured seat provides easier entry and exit, while height-adjustable footplates, secure heel captures, an ergonomic handle, durable belt drive, and active recoil system support smooth and comfortable rowing.

Built from commercial-grade steel and aluminum with a premium black finish, the S660 Forge is designed for high-use fitness facilities while remaining equally capable in a performance-focused home gym.

Natural Fluid Resistance

The S660's water-based resistance system creates a dynamic relationship between your effort and the resistance you feel.

Rather than relying solely on electronically selected resistance, fluid rowing responds naturally to the power of each stroke. Pull harder and faster and the water provides greater resistance; reduce your effort and the rowing experience becomes correspondingly lighter.

The result is a smooth rowing motion designed to reproduce the progressive resistance associated with moving an oar through water.

Five Resistance Levels for Greater Training Flexibility

The S660 adds another level of control through its 5-level Fluid Force system.

Changing the tank setting alters the baseline resistance profile, allowing different users to select a rowing feel appropriate for their strength, conditioning, and training goals.

Combined with the natural response of water resistance, this provides flexibility for endurance workouts, cardiovascular conditioning, high-intensity intervals, strength-focused rowing, and performance training.

Performance Monitor That Recognizes Resistance Changes

One of the S660 Forge's most useful technologies is its Bluetooth Auto-Adjust Interactive Performance Monitor.

The Auto Resistance Detection system recognizes the selected Fluid Force level and automatically correlates that setting with its performance calculations.

This allows you to change resistance without repeatedly reconfiguring the console, helping you stay focused on your workout.

Track the Metrics That Matter

The performance monitor displays key rowing information including time, speed, distance, stroke rate, calories per hour, watts, and resistance level.

Monitoring stroke rate and power together can be particularly useful when developing rowing technique, pacing workouts, or comparing performance between training sessions.

Designed for Easier Entry and Exit

The S660 uses an elevated seating position rather than placing the user close to floor level.

The higher position can make getting onto and off the rower more convenient, particularly for taller users or anyone who prefers the accessibility of a higher seat.

The contoured seat glides smoothly along the rail and incorporates a textured finish to help maintain a secure seating position.

Commercial-Grade Durability

The S660 Forge is designed for environments where fitness equipment may be used repeatedly throughout the day.

Its steel-and-aluminum construction, double-sealed twin tank, durable belt drive, active recoil system, and seat-rail cleaning brushes are all designed around long-term reliability.

That full-commercial construction also makes the S660 an excellent option for home users who want an especially robust rowing platform.

Compact Vertical Storage

Despite measuring approximately 85 inches long during use, the S660 can be positioned vertically for space-saving storage.

In its upright position, the machine requires a floor footprint of only approximately 27" × 20", helping reclaim valuable floor space between workouts.

Key Features

5-Level Fluid Force Resistance

Choose from five Fluid Force resistance levels to customize the feel and intensity of your rowing workout.

Variable Fluid Resistance

Dynamic Fluid Fitness's fluid-resistance system uses water to create smooth resistance that responds naturally to the amount of power applied during each stroke.

Updated High-Resistance Impeller

An updated impeller design provides approximately 15% greater resistance than previous designs, creating additional resistance potential for stronger and more experienced rowers.

Precision Twin-Tank Design

The double-sealed, precision-aligned twin-tank system is engineered with tight tolerances for consistent resistance and dependable commercial operation.

Bluetooth Auto-Adjust Performance Monitor

The advanced Bluetooth Auto-Adjust Interactive Performance Monitor combines workout tracking, Bluetooth connectivity, and automatic resistance detection.

Automatic Resistance Detection

Fluid Force Auto Adjust technology automatically correlates the selected tank resistance level with the performance monitor's calculations, eliminating the need to manually reprogram the console whenever resistance changes.

Comprehensive Workout Metrics

Monitor important performance information including:

• Time

• Speed

• Distance

• Stroke rate

• Calories per hour

• Watts

Bluetooth Connectivity

Bluetooth connectivity allows the performance monitor to communicate with compatible smart devices and supported fitness applications.

Heart Rate Receiver

An integrated heart-rate receiver supports compatible heart-rate belts for additional workout monitoring.

Elevated Seat Height

The elevated rowing position provides easier entry and exit than lower-profile rowing machines.

Contoured Non-Slip Seat

The contoured seat features a textured surface designed to reduce slipping while providing a smooth, quiet glide along the rail.

Height-Adjustable Footplates

Adjustable footplates help accommodate different users and provide appropriate foot positioning throughout the rowing stroke.

Secure Heel Captures

Integrated heel captures help maintain secure foot placement during both the drive and recovery portions of the stroke.

Premium Ergonomic Handle

The ergonomic rowing handle is designed to provide a secure, comfortable grip throughout longer and higher-intensity workouts.

Durable Belt Drive

A heavy-duty belt-drive system provides smooth power transfer without the feel or maintenance requirements associated with a conventional chain drive.

Active Recoil System

The integrated active recoil system provides smooth handle recovery as you transition between rowing strokes.
