Marcy SM-4903 Smith Machine Review: Smith Bar, Cage and Pulleys in One

The Ultrasport Power Rack puts spotter arms, a pull-up bar, a dip stand and a plate-loaded lat pulldown with a low row into one frame for £257.99 (2 October 2026), and it carries a 4 year warranty. Those features usually cost more. The catch is in the load ratings: 200kg on the spotters and 80kg on the pulley are fine for most home lifters but well below what a proper steel cage offers.
We rate it 3.8 out of 5. It's a lot of training for the money from a German brand that's been selling home fitness kit for years, and it suits beginners and intermediates far better than anyone already squatting heavy.
How we review
This review is based on research rather than hands-on testing. We worked from Ultrasport's Amazon UK listing and specifications, compared the rack with the power cages and multi gyms we've reviewed, and checked the strength training guidance from the NHS and WHO. We haven't assembled or lifted in this unit, so we report specs as Ultrasport states them and say where the listing is unclear.
Buy it if you're building a first home gym and want to cover squats, presses, pull-ups and back work in one go. The lat pulldown is the standout feature at this price. It lets you train the back muscles used in pull-ups even if you can't do one yet, then the pull-up bar is right there when you can.
It suits lifters with moderate goals too. The 200kg spotter rating comfortably covers a beginner's first two or three years of squatting and benching.
Skip it if you already squat or bench near 150kg, or you plan to drop weights onto the safeties regularly. Our best power cage UK guide covers heavier frames, and the WINNOW power cage is a sturdier option if you have more budget.
Check the Ultrasport Power Rack price on Amazon£257.99The outside footprint is 145.5cm by 141cm and the frame stands 213.5cm tall, with 105cm by 100cm of space inside. That's compact for a full rack, which helps in a box room or single garage. Ultrasport lists the rack at about 26kg, which is light for this much steel. Lighter frames rock more when you rerack a heavy bar or kip on the pull-up bar, so plan to bolt it down or at least put heavy plates on the base.
Spotter arms are the safety system. They adjust in height through the perforated uprights, so set them a few centimetres below the bottom of your squat or bench and a failed rep lands on the arms rather than on you. That's the whole point of training in a rack alone, and our pin squat guide shows how to use them as a training tool as well as a safety net.

The pulley is plate-loaded, with integrated footrests so you can brace for lat pulldowns and low seated cable rows without your body lifting off the seat. The 80kg limit covers most people's pulldown and row working weights for a long time. A heavy lifter will outgrow it, though, and Ultrasport doesn't say whether the pulley runs 1:1 or 2:1, which changes how the plates feel on the handle. You'll need your own bench or a seat for the pulldown.
Strength work isn't optional extra credit. The NHS recommends strengthening activities that work all the major muscle groups on at least two days a week, alongside 150 minutes of moderate activity, and the WHO guidance says the same for adults. A rack with pulleys covers every major muscle group in one footprint, which makes hitting that target far easier than a set of dumbbells alone. The NHS strength exercises page has bodyweight moves if you're starting from zero.
At £257.99, the Ultrasport undercuts most racks with a built-in lat pulldown. The SPORTNOW cable crossover power cage costs about £100 more and gives you twin cable columns and higher load ratings, which is the better buy if you're already lifting seriously. The Sunny Health Power Zone cage is the pick for heavier barbell work without cables. The Ultrasport wins on warranty and on getting everything into the smallest space.
See today's Ultrasport Power Rack priceUltrasport rates the spotters for standard or Olympic barbells and plates up to 200kg. Separate limits apply to the stations: 130kg on the pull-up bar, 100kg on the dip stand and 80kg of added weight on the lat and row pulley.
Yes, with adjustable spotter arms to catch a failed rep. The listing only names the two spotters as bar supports, so check the product images or ask the seller how you'll rack the bar at shoulder height before you order.
It stands 213.5cm tall, with an outside footprint of 145.5cm by 141cm. The inside working space is 105cm by 100cm with 205cm of height. You need a ceiling of roughly 2.4m to do full pull-ups without hitting your head.
No. Weights and the barbell are sold separately. It takes both 1 inch standard and 2 inch Olympic bars and plates, so you can use what you already own.
Amazon lists a 4 year manufacturer warranty, which is long for a rack at this price. Most budget racks come with 12 months to 2 years.
Yes. The 200kg spotter rating and 80kg pulley limit cover several years of progress for most home lifters, and the lat pulldown helps you build towards unassisted pull-ups. Stronger lifters squatting well over 150kg should look at a heavier cage.
