The assembled dimensions are 87” long by 21.5” wide by 23” high. Differently put, the unit needs a workout area with perimeters of 7’3” length by 1’8” width, plus an extra clearance of 2′ around for conduciveness.

Users whose inseams are less than 38” can fit in perfectly on this rower.

The Handlebar

It allows you to apply each stroke comfortably without fear of losing your grips, and neither will you experience any blisters in the palms after prolonged and consistent workouts.

The handlebar is attached to a durable nylon pulling cord that is connected to the flywheel.

The pedals

The pedals are large, and textured with adjustable safety nylon straps and heel guards. Hence, most foot sizes can be accommodated comfortably with optimum footing stability.

The Drive/Resistance

The SF-RW5508 Ultra Tension Magnetic Pro Rower is a belt-driven machine that is equipped with a manual magnetic resistance system.

This means the rower’s operation is smooth, quiet, and vibration-free. For this reason, users can workout without constituting a nuisance to anyone around them, and if they wish to watch a TV show or listen to music they can too.

The manual magnetic resistance system provides 1 to10 resistance levels for different workout challenges. It mainly comprises a metallic flywheel (weight not specified), and a magnetic pad.

So, resistance is generated when the magnetic brake pad emits magnetic fields around the flywheel without actual contact.

The tension knob is used to control the resistance intensity. Therefore, you can simply turn it clockwise or anti-clockwise to increase or decrease the resistance level, respectively.

Although, the resistance is not dynamic as a water or air resistance system, but it does provide fairly low-impact challenging workouts that could help users to burn calories, engage and tone most of the body’s muscle groups, and more.

No maintenance is required since none of the resistance system’s elements rubs, and so, no part wears out over time. Moreover, post lubrication or adjustment is not necessary as well.
