Body-Solid GFT100 Review (2027): The Default Dual Stack Trainer, Examined
Full research review of the Body-Solid GFT100: stack system and upgrade path, pulley feel, carriage range, footprint, and ownership themes.
Body-Solid GFT100 Functional Trainer
Dual 160 lb stacks, a 1:2 ratio, and swivel pulleys on a frame built for daily home use.
- Two 160 lb stacks, upgradeable to 210 lb per side
- Weight stack
- 1:2 (handle weight is half the selected stack)
- Pulley ratio
- 45.1 x 64.5 x 83 in (W x L x H, manufacturer listing)
- Footprint
Our verdict
The GFT100 earns its default status by having no weak chapter. The stacks are deep enough for years of training and upgradeable when they are not, the swivel pulleys behave on awkward angles like low to high flies, and the frame has the overbuilt feel owners describe across Body-Solid machines. Its honest costs are the 1:2 ceiling that strong rowers will eventually meet, a footprint that claims a wall outright, and an assembly that should be scheduled like a project. For a home gym buying one cable machine to serve a decade, those are the right compromises.
What we like
- Two independent 160 lb stacks with a published upgrade path to 210 lb per side
- Swivel pulleys and tall carriages give a wide, natural arc on flies and presses
- Selectorized changes are instant, which keeps supersets and paired training moving
What to watch out for
- The 1:2 ratio halves handle weight, so strong lifters can top out the stack on rows
- Assembled footprint plus working space needs a dedicated wall, not a spare corner
Who it is for
Home gym owners building around one selectorized trainer for full body accessory work, pressing variations, and cable rows.
Stacks, ratio, and the upgrade logic
Two 160 lb stacks at 1:2 give 80 lb per handle, or double clipped together for heavy two handed patterns. The factory 210 lb upgrade is the detail that separates this machine from closed rivals: the day the stack runs out, the answer is a parts order, not a new trainer. Pin changes are instant and identical on both sides, which sounds minor until two people train together.
Carriage range and cable feel
The pulleys travel the height of the uprights and swivel to meet the line of pull, so the same station sets truly low for kickbacks and truly high for overhead work. Owner feedback on glide is consistently positive, with the reinforced nylon pulley design credited for staying quiet under load.
Footprint and room behavior
At roughly 45 by 65 in, the frame wants a wall and about four clear feet in front of it. Inside that box it is a complete cable gym. The machine does not fold, narrow, or apologize, so measure the room, the door it enters through, and the assembly space before ordering.
Ownership themes
Long term reports emphasize stability: cables and pulleys wearing predictably, stacks staying smooth, and Body-Solid parts support being reachable. Complaints cluster on assembly effort and on very tall users wanting more travel overhead, both knowable in advance.

FAQ
Questions, answered straight
Does the GFT100 need to be bolted down?
Most owners train on it free standing; the loaded frame is heavy and stable for cable work. Follow the manual for your flooring and use case, and keep heavy off axis pulls within sensible limits.
What attachments does it work with?
Any standard carabiner cable attachment: D handles, ropes, straight and curl bars, ankle straps. The swivel pulleys accept the whole standard ecosystem without adapters.
How hard is assembly, honestly?
Plan on several hours and a second person. The frame, two stacks, and cable routing reward patience and a sorted hardware layout. Owners who rush cable routing are the ones who redo it.
