If you're outfitting a commercial gym floor and need one machine that can serve four to eight members training different muscle groups at once, the Body-Solid SJG Jungle Gym is one of the most space-efficient answers on the market. In this Body-Solid SJG Jungle Gym review, we'll break down the three available configurations — the 4-stack SJG100, the 5-stack SJG500, and the 8-stack SJG800 — so you can figure out which one actually fits your facility and your budget.
Unlike a single-stack home gym, the Jungle Gym line is built around simultaneous, multi-user training: several members can press, pull, curl, and extend on the same frame without waiting for a turn. That makes it a mainstay in fitness centers, apartment and community gyms, and strength and conditioning facilities that need to move a lot of people through a workout in a limited footprint.
Body-Solid SJG Jungle Gym: The Basics
Price: Starting around $7,400, with the full SJG line ranging roughly $7,500–$16,000 depending on configuration | Weight Stacks: 210 lb. or 310 lb. per station | Warranty: Body-Solid Full Commercial/Lifetime Warranty
All three SJG configurations share the same core engineering: a commercial-grade steel frame with independent weight stacks per station, so one member's leg press doesn't affect another's lat pulldown. Each station can be specified with either a 210 lb. or 310 lb. weight stack, which matters a lot if your facility skews toward serious strength athletes rather than general fitness members.
SJG100: The 4-Stack Configuration
Footprint: 62"L x 137"W x 89"H | Product Weight: 1,329 lbs. | Stations: 4
The SJG100 is the entry point into the Jungle Gym family and the most realistic option for a boutique studio, hotel fitness center, or smaller commercial floor that still needs multi-station capacity without dedicating a huge chunk of square footage to it. At 137" wide, it's still a serious commercial installation — plan for a dedicated wall or floor zone — but it's meaningfully more compact than the 5- and 8-stack versions.
Best for: Smaller commercial facilities, hotel and apartment fitness centers, and studios that want true multi-station simultaneous training without committing to an 8-stack footprint.
SJG500: The 5-Stack Configuration
Footprint: 137"L x 181"W x 89"H | Product Weight: 1,521 lbs. | Stations: 5
The SJG500 steps up to five independent stations in a wider footprint, giving mid-sized commercial gyms an extra station of throughput without jumping all the way to the 8-stack SJG800. If your facility runs group circuit classes or has consistent peak-hour congestion on multi-station equipment, the extra station on the SJG500 can meaningfully cut wait times.
Best for: Mid-sized commercial gyms and fitness centers that have outgrown a 4-stack unit but don't need full 8-station capacity.
SJG800: The 8-Stack Configuration
Footprint: 165"L x 201"W x 89"H | Product Weight: 3,098 lbs. | Stations: 8
The SJG800 is the flagship of the line — a full 8-station commercial rig weighing over 3,000 lbs. that's designed for high-volume clubs, university rec centers, and large-format gyms where a dozen members might be working the machine during peak hours. This is a serious facility investment, both in cost and in the floor space and structural planning (loading dock access, floor load rating) it requires.
Best for: Large commercial clubs, university and corporate rec centers, and high-traffic facilities that need maximum simultaneous-user capacity from a single multi-stack unit.
210 lb. vs. 310 lb. Weight Stacks: Which Should You Choose?
Every station across the SJG100, SJG500, and SJG800 can be configured with either a 210 lb. or a 310 lb. weight stack. For a general-population commercial gym — think apartment complexes, hotels, or a mixed-membership fitness center — the 210 lb. stack covers the vast majority of members comfortably. If your facility caters to a strength-focused membership, a CrossFit-adjacent program, or athletic training groups where advanced lifters will be loading up leg press or lat pulldown stations, the 310 lb. stack gives you meaningfully more headroom before someone needs to stack plates on top of the weight horn, which most commercial gyms prefer to avoid for liability and equipment-wear reasons.
Facility Planning: Space, Flooring, and Delivery
Because the SJG family ships via freight and weighs over half a ton even in the smallest SJG100 configuration, treat this as a commercial installation project, not a self-assembly weekend project. Confirm loading dock or forklift access at your facility, verify your flooring can handle a concentrated static load in the 1,300–3,100 lb. range depending on configuration, and plan the surrounding walkway space — members need clearance to load plates, sit on attachments, and move between stations, especially on the wider SJG500 and SJG800 units. Most commercial buyers coordinate delivery timing with their assembly crew so the unit goes straight from the dock to its final footprint.

Frequently Asked Questions
What's the difference between the SJG100, SJG500, and SJG800?
They're the same core Jungle Gym engineering scaled to different station counts: the SJG100 has 4 stations, the SJG500 has 5, and the SJG800 has 8. Footprint and product weight scale up accordingly, from 1,329 lbs. for the SJG100 to 3,098 lbs. for the SJG800.
How much does the Body-Solid SJG Jungle Gym cost?
Pricing starts around $7,400 for the base configuration and ranges up to roughly $16,000 depending on stack count and weight stack size (210 lb. vs. 310 lb.).
Should I choose 210 lb. or 310 lb. weight stacks?
210 lb. stacks suit general-population commercial gyms and mixed-membership facilities. 310 lb. stacks are worth the upgrade for strength-focused programs or athletic training facilities where members regularly need more resistance.
