Q: What is the difference between the Functional Trainer Rack (FTR) and the Tandem Tower (TT)?

Both are 3x3 in / 76 mm, 11-gauge steel cable machines from the same CORNERSTONE family. The Functional Trainer Rack ($3,399) is a functional trainer built into a half rack: dual cable pulleys plus Quick-Lock J-Cups and 2,000 lb / 907 kg rated spotter arms, so you can squat, bench, and rack a barbell in the same footprint. The Tandem Tower ($2,499) is a pure cable system with two pulleys on separate uprights, which unlocks a selectable 2:1 or 1:1 ratio and a path to a full crossover. Choose the FTR for cables plus barbell training; choose the Tandem Tower if cables are your priority.

Q: What attachments are included, and which do I need to buy separately?

Each machine ships ready to train. The FTR includes pull-up handles, Quick-Lock J-Cups, two 2,000 lb / 907 kg Quick-Lock spotter arms, a tricep rope, single handles, ankle cuffs, carabiners, band pegs, a barbell holder, and a storage pegboard. The Tandem Tower includes an aluminum revolving lat pulldown bar, a close-grip and landmine handle, single handles, a low-row footplate, and carabiners. Optional add-ons include the dip handles, lat bars, the Swivel Seat and Sliding Bench, and weight-stack upgrades. Both use our open 3x3 ecosystem with 1 in / 25.4 mm holes on 2 in / 51 mm spacing, so they accept Force USA and many third-party 3x3 attachments. They do not fit our older G-Series attachments, so check the 3x3 fit before ordering a part.

Q: How much weight do they come with, and can I upgrade the stack?

The FTR comes with dual integrated 200 lb / 90.7 kg weight stacks, one per pulley, each upgradeable by 50 lb / 22.7 kg. The Tandem Tower comes with a 200 lb / 90.7 kg stack, upgradeable to 250 lb / 113 kg. Both run 5 lb / 2.3 kg fractional plates for smaller jumps between the main plates, so you can progress in precise increments. For safety, do not exceed the stack's intended maximum, even with aftermarket pins.

Q: How much space do I need, and what about ceiling height?

The FTR footprint is 49 in W x 43 in D x 87 in H / 124.5 x 109.2 x 221 cm, and you want about 94 in / 238.8 cm of ceiling for a full chin-up. The Tandem Tower is 53 in W x 58.5 in D x 87 in H / 134.6 x 148.6 x 221 cm and stands 87 in / 221 cm tall, so leave at least 3 in / 7.6 cm of clearance above it. For safe heavy training we recommend anchoring to the floor where possible; the spotter arms and Quick-Lock J-Cups are rated for serious load, and a bolted base keeps everything rock-solid under a working barbell.

Q: How are they shipped, and how long does assembly take?

Both ship as freight on a pallet and arrive curbside in heavy-duty wooden crates: the FTR around 1,000 lb / 454 kg in two crates, the Tandem Tower around 835 lb / 379 kg in two crates. Plan on 3 to 5 hours of assembly depending on your experience. Every tool, fastener, and the step-by-step instructions are in the box, and a professional assembly upgrade is available at checkout if you would rather have it built for you. We recommend using your own power tools to speed up the process, and take care not to overtighten any bolts.

Q: Can a functional trainer replace free weights or a full gym?

For most home gym goals, yes, and the FTR goes a step further by adding a true barbell half rack on top of the cables. Functional trainers build real muscle and strength through a full range of motion, with constant cable tension that is easy on the joints. The cable path also makes solo training safer than maxing out a loaded barbell with no spotter. If you want both cables and heavy barbell work in one machine, the FTR is purpose-built for exactly that. And if cables are your focus, the Tandem Tower is a serious functional trainer in its own right: two independent pulleys on separate uprights give you a selectable 2:1 or 1:1 ratio, mirrored left and right stations for balanced training, and full-height adjustability, so it covers nearly every pulling, pressing, and core movement you can name, from heavy lat pulldowns to cable flyes to woodchops. Add the Cross Beam Connector Set and it grows into a full commercial-style crossover.

Q: What warranty comes with them, and where are they made?

Both machines are designed and engineered in the US and carry our standard home warranty: Lifetime Frame, 10 years on moving parts, and 1 year on upholstery and attachments. A separate commercial warranty applies to commercial-rated equipment. They are backed by strong owner ratings, with the FTR at 4.8 and the Tandem Tower at 4.9. Both are part of the CORNERSTONE 3x3 lineup, the foundation your whole gym can be built on.

A functional trainer is a dual pulley cable machine that lets you press, pull, rotate, and resist from any angle in one compact footprint, which makes it a serious strength tool for any home or studio gym. Whether you're building muscle, training for sport, or developing the kind of off-axis strength that carries into real life, a functional trainer puts the work in your hands.

Every Force USA functional trainer is precision-engineered with 11-gauge steel, 3"x3" uprights, and aircraft-grade cables rated to 2,000 lb. Polished aluminum pulleys deliver glass-smooth travel, and each pulley runs at 2:1 for speed and range. Connect both cables to a single load for a true 1:1 ratio when you want maximum resistance. Enclosed weight stacks and captured cables mean you can train hard alone without thinking twice.

Force USA offers two: the Functional Trainer Rack (FTR), a functional trainer built into a half rack with Quick-Lock J-hooks and rated spotter arms for squats, bench, and cables in one footprint; and the Tandem Tower (TT), a pure dual-pulley cable machine with two independent pulleys that make connecting both cables for a true 1:1 ratio simple, plus a path to a full crossover.

What is a functional trainer, and what can I do on one?

A functional trainer is a dual-pulley cable machine that lets you press, pull, rotate, and resist from almost any angle. Two adjustable pulleys in one compact footprint replace a wall of single-station machines: chest press and flys, lat pulldowns, rows, cable curls, triceps pushdowns, woodchops, face pulls, and the off-axis core and rotational work that transfers straight to sport and real life. Because the cables guide the load on a fixed path, you can train hard on your own with far less risk than loading a heavy barbell solo.
