The CDC physical activity guidelines for adults recommend at least 150 minutes of moderate aerobic activity a week, and steady rowing sessions count toward it. In a study of 107 adults aged 20 to 74, rowing on an ergometer used more energy than cycling at the same power output.
Sunny Health & Fitness SF-RW5940SMART FitScore
FitScore rates each rowing machine on its specs, weighted for one buying intent (how we score). The SF-RW5940SMART is #2 in our best rowing machine under $1,000 guide, so this review uses that guide’s weights. Performance and durability count most (28% each), then comfort (17%), practicality and features (11% each) and affordability (5%). Under $1,000 the rower has to row well and last, with a good fit close behind.
FitScore for Rowers Under $1,000
How this FitScore was calculated
This FitScore combines 6 category scores using the weights of the buying intent above.
- Performance (93): air plus magnetic resistance with 16 levels, and a monitor with a 500 m split, stroke rate and pulse.
- Durability (62.14): a 300-lb rating and three years on the frame, held back by 180 days on parts.
- Comfort (85): a 52.6-inch rail for rowers up to 6 ft 9 in.
- Practicality (76): it folds and rolls away, but it is 91.3 inches long in use and weighs 81.6 lb.
- Features (70) and affordability (60): Bluetooth, the free SunnyFit app, pulse and a device holder; mid-range value among the rowers we rank.
Design and Build Quality
The SF-RW5940SMART uses an alloy steel frame with a 52.6-inch rail, a folding joint and wheels. At 81.6 lb it is a full-size rower that still stands away when you are done.
Owners describe it as sturdy and good value, and find assembly easy with clear directions. Durability reports are mixed: most say it holds up well, while a few had a part fail early, so register it and test every level in the first weeks.
The folding joint is the part to look after. Lock it fully before each session, and check its pin and the frame bolts every few weeks, since a slight wobble usually comes from a bolt that has settled after the first rows rather than from the frame itself.
Bottom line: a full-size frame that still folds.
Resistance and Rowing Feel
The fan adds load as you pull harder, like an air rower, and the magnet brake sets a base level across 16 steps. You get a pull that rises with your effort and a level you can fix for steady work.
Owners describe the stroke as smooth and quieter than a pure fan rower. Opinions on the workout itself are split, so if you want the classic air feel, compare it with an air rower in our air vs magnetic rowing machine guide.
Bottom line: smooth, with load that rises with effort.
Fit, Rail and Seat
The 52.6-inch rail is long for its class, and the rower is listed for users up to 6 ft 9 in, which suits tall rowers.
The 300-lb rating is the limit: heavier users should look at the 440 to 500-lb air rowers in the same guide.
Set the foot straps so they cross the widest part of your foot, then check that your legs reach full extension with a slight bend left at the knee. Owners find the seat comfortable for most sessions; a thin cushion helps if you row for 30 minutes or more.
Bottom line: a long rail for tall rowers, a mid rating.
Monitor, App and Connectivity
The monitor shows time, distance, strokes, calories, stroke rate, the 500 m split and pulse, which covers pacing and heart-rate training without a strap.
Bluetooth links the rower to the free SunnyFit app, with no membership needed, and a device holder keeps a phone or tablet in view.
The split is the number to train with. Pick a 500 m split you can hold for 20 minutes, then row intervals a few seconds faster with easy rows between them. The pulse reading lets you keep steady sessions at a conversational effort and push only on interval days. The SunnyFit app logs each session, so you can watch your 2,000-meter time and your average split improve over the weeks without paying for a plan.
Bottom line: a complete monitor and a free app.
Footprint, Storage and Noise
In use it measures 91.3 × 22 inches, so plan a long strip of floor. Folded, it stands on its end and rolls on its wheels.
Owners find folding easy, though a few found it stiff at first. The fan adds some whoosh, but owners describe it as quieter than a fan-only rower.
Leave about two feet of clear floor behind the seat and at the sides, and row on a dense rubber mat to protect the floor and cut vibration. In an apartment, keep the hardest fan efforts for times when noise matters less; the magnet levels let you add load without much extra sound.
Bottom line: long in use, compact stored.
Setup, Warranty and Support
Coverage is three years on the frame and 180 days on parts. Keep your order details and contact Sunny customer service if anything fails early.
Assembly is straightforward for most owners, with clear directions. Build it near where it will live, since it weighs 81.6 lb, and ask a second person to hold the rail while you join it to the frame.
In the first week, test all 16 levels, fold and unfold it a few times and confirm the monitor reads strokes and pulse. Then wipe the rail after each session and check the bolts every few weeks; that routine keeps the seat gliding smoothly and catches early faults while the parts term still applies.
Bottom line: good frame cover, short parts term.
