Body-Solid Pro ClubLine Leg Curl and Extension Machine (S2LECX)
The S2LECX is a full commercial machine that trains quads and hamstrings from one seat. You do seated leg extensions, swing the pad over, and do prone leg curls without getting up and without walking to a second station.
It occupies 54 by 52 inches of floor, which is about 19.5 square feet. That is the number to judge this machine on. A standalone leg extension plus a standalone leg curl means two frames, two stacks, and roughly twice the floor space for the same two movements. On a crowded gym floor that difference is worth more than the price gap.
Body-Solid renamed this machine from S2LEC to S2LECX. It is the same machine with the same published specs. Both codes are listed on this page so either one finds it.
Which weight stack should you pick?
Pick by how big a jump your users can handle, not just by the top number. Both stacks hold the same 16 plates. The 160 lb. stack uses 10 lb. plates. The 235 lb. stack uses 15 lb. plates.
So the bigger stack does not add plates. It makes each plate heavier, which means every jump on the pin gets 50 percent bigger. On leg extensions that matters more than most people expect, because a 15 lb. step is a large move for a single joint.

Rehab, youth, senior and general membership |
Athletes and strong general membership |
Take the 160 lb. stack if you run physical therapy, youth programs, senior fitness, or a broad membership. The 10 lb. steps let people land on a weight that is actually right for them instead of choosing between too light and too heavy.
Take the 235 lb. stack if you train athletes or serve a strong membership. Trained lifters run out of a 160 lb. stack on leg extensions faster than they do on almost any other machine.
How much room does it need?
The frame occupies 54 in. by 52 in. Both stack sizes are identical, so the footprint does not change with your choice.
Allow about 2 ft. of clear floor on the entry side and behind the frame so people can step in and out and so the extension arc is not blocked. Plan on roughly 8 ft. by 7 ft. of total floor.
Ceiling height is not a constraint here. The machine stands 57 in. tall, which clears any standard ceiling with room to spare. That is one reason it works in basements and low ceiling rooms where a lat tower will not fit.
What is it built from?
-
Mainframe: 2 in. by 3 in. steel tubing at 11 gauge, welded on all four sides rather than tacked.
-
Weight stack: selectorized and fully shrouded, so the plates are enclosed on all sides.
-
Upholstery: Body-Solid DuraFirm pads, extra thick commercial density, on the seat, thigh pad and ankle rollers.
-
Adjustments: the thigh pad and ankle roller both move to fit different leg lengths, and there are stabilizing hand grips at the seat.
-
Finish: black.
What does it look like in use?
This clip runs through both movements on the machine, the seated extension and the prone curl, including the pad changeover between them.
Who should skip it?
If two people need to train legs at the same time, a combo machine becomes a bottleneck. One person on the extension blocks the curl. Two standalone machines cost more and take more floor, but they run in parallel.
If your users need steps smaller than 10 lb., neither stack will give you that. You would need add on micro plates, which Body-Solid does not supply for this frame.
And if your delivery point has no hard level surface for a pallet jack, sort that out before you order. The heaviest single carton weighs 313 lb.
Frequently asked questions
What is the real difference between the 160 lb. and 235 lb. stacks?
The step size. Both hold 16 plates. The 160 lb. version uses 10 lb. plates and moves in 10 lb. jumps. The 235 lb. version uses 15 lb. plates and moves in 15 lb. jumps, starting from 10 lb. on the top plate.
Can I upgrade the stack later?
Not by adding plates. Because both stacks hold the same 16 plates, going from 160 lb. to 235 lb. means replacing 15 plates rather than stacking more on. Choose the stack when you order.
How many pieces does it ship in?
Five. Two cartons hold the frame and shroud, at 313 lb. and 53 lb. The weight plates ship separately in three more cartons. Count all five at the curb before you sign, because the plate cartons are easy to overlook next to the two large ones.
Does it come assembled?
No. The manual walks through 8 steps. Body-Solid does not publish an assembly time, but plan on two people and most of an afternoon. You supply the tools: metric and standard Allen keys, metric and standard wrenches, an adjustable wrench, and both screwdriver types.
What happened to the S2LEC?
Body-Solid renamed it S2LECX. Same machine, same dimensions, same weights, same warranty. The part numbers changed from S2LEC/1 and S2LEC/2 to S2LECX/1 and S2LECX/2. The owner's manual and parts schematic are still published under the S2LEC filename and are the current documents.
What does the warranty cover?
In a commercial setting the frame and welds are covered for life, pulleys, bushings, bearings, hardware, plates and guide rods for 3 years, and cables, upholstery and grips for 1 year. In a home setting every one of those parts is covered for life. Full terms are in the Warranty tab on this page.
Is it overkill for a home gym?
It is priced and built for commercial floors, so it costs more than a home leg machine. What you get for that is the lifetime home warranty on every part and a frame that will outlive the room. It fits a home only if you have the floor and the ceiling is not the issue, since it stands just 57 in. tall.
How does it ship?
Free freight, curbside, with liftgate service included. Delivery details and lead time are in the Shipping and Returns tab.
Bottom line
If you need both leg extension and leg curl but only have room for one machine, the S2LECX is the answer at about 19.5 square feet. Choose the 160 lb. stack for smaller jumps and broader users, and the 235 lb. stack for stronger ones. Our team can help you decide before you order.
