SF-RW5639 – Sunny Health & Fitness Review

Sunny Health & Fitness SF-RW5639 Review

The Sunny Health & Fitness SF-RW5639 Full Motion Rowing worked like a lifesaver for many customers. With a digital monitor screen, you can track your day-to-day progress, which boosts your regular workout efforts.

This rowing machine is built with hydraulic-piston resistance and “free-motion” rowing arms which provide you the ultimate feel of rowing a boat! The rower is equipped with a fully padded seat, nonslip handlebars, and anti-slip foot pedals with an adjustable strap.

One of the appealing aspects of this rower is, it comes with a very strong steel frame that can hold 350 lbs weight capacity very easily. Usually, low-end rowing machines won’t have that high of a weight capacity, which makes this SF-RW5639 one of the most reliable entry-level rowing machines out there. Let’s move forward with the whole review.

Feature Analysis

1. Digital Monitor

Tracking your day-to-day progress is simple with an LCD digital monitor screen. This monitor can track time, Count ( of Strokes), Total Count (Total Strokes), and calories. The auto shut-off technology off the monitor after 4 minutes of inactivity. It runs on 2AAA batteries which are included.

2. Hydraulic Cylinder Resistance

The Sunny Health SF-RW5639 comes with one hydraulic piston which means, the resistance is controlled by a single piston located beneath the seat rail. The cylinders are filled with hydraulic fluid while you pull it back thus, this machine provides you a great workout.

3. Foot Pedals

This rower comes with Foot Pedals; this non-slip foot pedal will ensure your safety and momentum while doing the workout. With an adjustable Foot strap, you can quickly focus on the workout without feeling unbalanced.

4. Cushioned Seating

Comfort controls overall satisfaction of a user. So manufacturer made this rowing machine covered with extra padding and cushion to ensure proper blood flow while you do a prolonged or tough workout. This extra padding helps to release your pressure point.

  • Resistance can fell weak for strong users

Final Verdict

The Sunny Health & Fitness SF-RW5639 is one of the top sports for entry-level rowing machines. The machine includes 12 easy-to-adjust hydraulic resistance features, an increased weight limit, a good LCD digital tracking system, foot pedals, and a lot more comfort that makes this rower a very good entry-level investment.

Some people object that they felt very light resistance as because some of these users mix up between weightlifting exercise and rower. A rower will not provide all of the weightlifting exercises. And others are perhaps too fit for this model.

Overall, we feel this is a great rowing machine for the right person. So you have to choose among the models to get what right for you. So, cheers for a healthy life!

Among my friends and relatives, I got a lot of people who went to the gym, took exercises for months or years, and had patience to see a fit, strong, and perfect body, but in vain. Some of them used to complain against the instructors while some of them against the equipment and tools. However, nobody would talk about the diet and nutrition they were receiving. How could they tell? I guess most of them didn’t have the idea that a balanced diet should be the foremost thing to ensure while working out regularly. Here I got the motivation to go ahead with the subject. Truly speaking, I enjoy working on this track because it feels like helping out those who really need. Are you one of them?
