Sunny SF-RW5515 Rowing Machine: Resistance Type

Sunny SF-RW5515 Rowing Machine in More Detail

The Sunny SF-RW5515 comes with eight distinct resistance levels. All levels are easily adjustable; you just turn the knob mounted on the center panel.

For beginners and unaccustomed users, level 1 is the most suitable and works great for them, whereas level 8 will grant even the most experienced athlete a remarkable workout.

To adjust the resistance level, you turn the knob clockwise from level one all along to level eight. As you adjust, the magnet in the flywheel will automatically shift and move closer to the drum. The closer the magnet gets to the drum, the more resistance is generated.

Sunny Health & Fitness has it to their customers that they’ve introduced an advanced magnetic tension system along with the SF-RW5515. There’s much info about what this entails, but most users tend to agree, according to their supportive remarks.

The resistance is easy to operate, and all it takes is just to turn the knob either right or left until you’re satisfied. The only drawback is you have to pause the rowing to regulate the tension, but reasonably this is not a significant problem.

The notable difference between air and magnetic resistance systems is that when rowing on an air resistance machine, the strength adjusts based on your rowing intensity and speed.

The fact may create some odd transition between the two forms because magnetic rowers provide constant tension, and it depends on the set resistance level.

It’s an excellent rowing tool for persons who want an adaptable tension so that they can endure a potential resistance at a moderate pace. Plus, the model is incredibly priced.
