The Landmark K2S Stealth is a budget-oriented all-in-one home gym that gives you articulating cable arms, a power rack, a Smith machine, and dedicated center pulleys at a lower cost than many loaded 3x3 systems, and it makes the most sense for someone who wants that functionality now rather than a rack they plan to customize for years. The trade is straightforward: the K2S looks and feels more basic in several places than pricier systems in this category, but its core exercise options are unusually complete for this category.
Quick Takeaway
The feature I keep coming back to is the adjustable pivot-arm cable system. The arms move easily, swing left to right, and let me set a much narrower or wider cable start point than a fixed functional trainer. Add a center lat pulldown and low row that combine the two stacks, a built-in Smith machine, free-bar capability, and a useful collection of included attachments, and this can cover a lot of training in one piece of equipment.
It is not a cheap rack in the ordinary sense, and the included attachments, center stations, and finish are clearly built to a price. Still, the front functional-trainer action was better than I expected. If your priority is high-end fit and finish or a broad aftermarket of rack accessories, I would look at a standard 3x3 platform instead. If your priority is getting the major movements and flexible cable angles without stepping into the pricing of more premium all-in-one racks, the K2S deserves a close look.

My Real-World Experience
I reviewed the K2S as the pared-back alternative to the loaded articulating-arm racks that have become popular. It is not a 3x3 rack: Landmark lists 60 mm uprights and 12-gauge steel, versus the 3x3, 11-gauge format common on more expensive systems. In my assessment, that difference is more about simpler components, overall finish, and future attachment compatibility than a missing core movement pattern.
Pivot Arms Change the Cable Setup
The front arms are the main reason to consider the K2S over a more conventional cable rack. Each arm rides on four rollers and was easy for me to move vertically with one hand using the pop pin. The arms also swing left to right through 180 degrees. I counted nine angle settings, and the bearings made the adjustment feel notably easy rather than something I had to fight between sets.
That range changes where the cable begins. I could swing both arms inward for close-grip cable work, keep them straight for a more familiar rack-based functional-trainer setup, or spread them outward for a wider cable path. That flexibility is useful for cross-body triceps work, curls, fly variations, and sharing the two sides with a training partner. A fixed cable exit can still work well, but these arms let you tailor the starting point to the movement instead of adapting every movement to the rack.
On the K2S I reviewed, the front functional-trainer pulleys were surprisingly smooth even without the optional aluminum-pulley upgrade; I would put them around an 8 out of 10. Landmark offers nylon and aluminum pulley options, but based on this experience, I would not treat the upgrade as mandatory. The center cable paths introduce more pulleys, and I found those closer to a 7 out of 10. They were still usable, just not as refined as the front action.
Center Lat Pulldown and Low Row
The K2S solves a common cable-rack limitation in a practical way. At the front arms, the 2:1 ratio means more cable travel and smaller effective jumps. With the 200-pound stacks I demonstrated, a 10-pound pin setting feels like roughly 5 pounds at the handle, and a fully selected 200-pound stack feels like roughly 100 pounds. That is useful for many cable movements, but it can run short for a heavier pulldown or row.
The dedicated center high and low pulleys combine both stacks. With 200 pounds selected on each side in my tested configuration, the center station delivers 200 pounds of 1:1 resistance. The top plate also accepts the included add-on horns. I measured about 7.75 inches of usable horn length on either side, so plates can add more resistance if needed. That is a meaningful advantage of this layout: you do not have to reposition the front arms and improvise a heavy center pull.
The low-row footplate adjusts fore and aft and gave me enough room to row, although it can wobble side to side even when tightened. That is representative of the K2S as a whole: it provides the function, while the execution is visibly and physically more basic than on more expensive machines.
At 6'2", I got a full lat-pulldown range of motion with about an inch to spare using the included knee holder on the spotter arms. In my review, removing the upper joiner bracket created more clearance, but it is structural hardware and I do not recommend removing it. Taller buyers should ask Landmark to confirm a manufacturer-approved configuration and their required pulldown clearance before ordering.
Smith Machine and Rack Function
The Smith machine is included, works as intended, and fits the K2S theme. Its range is constrained by the rack geometry: at my height, the top working position was below where I would ideally store the bar while moving around the rack, and the lower range began a little below my kneecap. For certain low starting movements, I would use a step-up platform. This is not unusual for rack-integrated Smith machines, but it is a real consideration if that feature is central to your purchase.
For barbell training, I would use the J-cups and spotter arms as supplied. Landmark lists a 1,000-pound Smith capacity and 1,500-plus-pound J-hook/spotter capacity, but those are manufacturer ratings rather than my independent load tests. The practical point is that this is designed as a complete starting station, not an empty frame that demands a cart full of add-ons.
Build Quality, Storage, and Long-Term Flexibility
The central question is not whether the K2S can perform a lot of exercises—it can. It is whether you will be satisfied with this configuration as your home gym evolves. The 2.4 x 2.4-inch uprights are more proprietary than the widespread 3x3 ecosystem. You can still change ordinary cable handles, but adding a different company’s J-cups, safeties, storage, specialty seat, or other rack-mounted accessory is more restrictive.
That makes the K2S a better fit for someone who wants a mostly finished all-in-one solution. It is less compelling for the person who sees a rack as an ongoing build project. The rear cross-post, storage hooks, plate horns, and locations for the J-cups and spotter arms help keep the included gear organized, but they do not change the compatibility question.
Comparisons / Alternatives
The direct alternative is a more expensive 3x3 articulating-arm all-in-one rack, including Landmark’s larger Everest. Those systems usually bring heavier uprights, a more refined finish, and a friendlier attachment ecosystem. I would choose that route if future add-ons and premium details matter as much as the all-in-one concept itself.
A conventional fixed-arm functional-trainer rack can be a simpler or more compatible alternative, but it will not duplicate the K2S’s movable cable start points. If heavy pulldowns or rows matter, compare its center-pulley arrangement carefully as well. In my review, I described the K2S as roughly $1,000 to $1,500 below comparable articulating-arm options. That was a review-time comparison, not a current price claim; configurations, promotions, and included accessories change.
Tradeoffs
The frame, attachment finish, and center pulley hardware are utilitarian rather than premium.
The low-row footplate can move side to side, and the center cable paths are less smooth than the front arms.
The integrated Smith machine has limited high and low range compared with a standalone unit; some exercises may need a platform.
The 60 mm rack format limits the pool of compatible aftermarket rack attachments.
It remains a major purchase. In my review, I quoted roughly $2,599 for 165-pound polymer-coated stacks, about $3,198 for the 198/200-pound steel configuration shown, and about $3,398 for 264/265-pound steel stacks. Those were review-time figures; verify the selected configuration and current checkout price.
Who Should Buy This
Buy the K2S Stealth if you want a broad menu of cable, barbell, Smith-machine, pulldown, and low-row work in one setup and you value adjustable cable angles. It is especially sensible for a buyer who would rather receive the core accessories up front than build a rack piece by piece. The center 1:1 stations and the pivot arms are the features that separate it from a simpler functional trainer.
Who Should Skip It
Skip it if the primary goal is to build an increasingly customized rack with a large third-party attachment market; start with a 3x3 rack system instead. I would also look elsewhere if you want a highly refined low-row station, need a Smith machine with a more accommodating range, or expect every included handle and attachment to feel upgraded out of the box.
Common Questions
Does the K2S have a true 1:1 cable ratio for heavy pulldowns and rows?
The front pivot arms are 2:1, so the 200-pound stacks shown in my review produced about 100 pounds of resistance per front handle at full selection. At the center high and low pulleys, the linked routing contributes about 100 pounds from each of two fully selected 200-pound stacks, for 200 pounds total—not 400 pounds. The available load depends on the stack option selected.
Can a tall person use the K2S for lat pulldowns?
At 6'2", I had a full range of motion with roughly an inch to spare using the included knee holder. I observed more clearance after removing the upper joiner bracket, but I do not recommend removing structural hardware. Taller buyers should confirm a manufacturer-approved setup and clearance with Landmark before ordering.
Can I add regular rack attachments later?
Some general cable attachments will work, but the K2S uses 60 mm uprights rather than the more common 3x3 format. Confirm compatibility for any J-cups, safeties, storage, or specialty rack-mounted attachment before buying it.
Final Verdict
The Landmark K2S Stealth gives you the exercises and adjustable-cable flexibility that matter most in a current all-in-one home gym without asking you to pay for the most polished version of the concept. I would take its front pivot arms and center 1:1 stations over a bare fixed-cable rack if those movements are priorities. Just go in clear-eyed: you are buying functional breadth and sensible pricing relative to more loaded systems, not a premium attachment ecosystem or the finest finish in the category.
