The Body-Solid Fusion 500 and Fusion 600 are two of the most popular multi-station home gyms on the market. Both offer commercial-grade construction, a 210 lb selectorized weight stack, and the kind of exercise variety that replaces an entire gym membership. But they're not the same machine.
If you're trying to decide between the two, this guide breaks down exactly what's different, what's the same, and which one is the better fit for your training goals and space.
What They Have in Common
Both the Fusion 500 and Fusion 600 share the same DNA. They're built on Body-Solid's heavy-gauge steel frames with the same 210 lb weight stack, premium nylon bushings for smooth operation, and DuraFirm padded seats. Both come with Body-Solid's industry-leading lifetime warranty. And both are designed to deliver a complete strength training workout from a single machine.
They also share the same core stations: a high pulley for lat pulldowns and tricep work, a low pulley for rows and curls, and a leg developer for leg extensions. The differences come down to the press arm system and functional training capabilities.
The Key Difference: Press Arms
Fusion 500 features synchronized articulating functional training arms. These arms offer 160 degrees of adjustability in 20-degree increments, letting you perform pec flys, converging presses, and functional cable movements that mimic real athletic movement patterns. The arms move from upper-abdominal height to side-access functional positions. Think of it as a hybrid between a traditional home gym and a functional trainer.
Fusion 600 features bi-angular press arms — the same patented technology found in Body-Solid's higher-end home gyms. The bi-angular system uses two independent press arms that move through a natural arc, providing a deeper muscle contraction at the top of each rep compared to a standard linear press arm. This is more focused on traditional strength training movements — chest press, incline press, shoulder press, and decline press — with a more natural feel than machines that lock you into a fixed plane of motion.
Head-to-Head Comparison
Exercise Count: The Fusion 500 offers 60+ exercises thanks to its functional training arms. The Fusion 600 offers 50+ exercises with its bi-angular press system. Both numbers are more than enough for a complete training program.
Training Style: The Fusion 500 leans toward functional and athletic training — if you want cable flys, rotational movements, and exercises that work stabilizer muscles, the 500 is the better choice. The Fusion 600 leans toward traditional bodybuilding-style training — if you want heavy chest presses, shoulder presses, and the deepest possible muscle contraction on pressing movements, the 600 delivers that.
Footprint: Both machines have similar footprints, roughly 4 feet wide by 6 feet deep. Neither requires significantly more space than the other.
Weight Stack: Both come with a 210 lb selectorized weight stack. Both can be upgraded with Body-Solid's optional weight stack extension kit if you need more resistance.
Price: The Fusion 600 typically costs more than the Fusion 500 due to the bi-angular press arm system, which is more complex to engineer and manufacture.
Who Should Buy the Fusion 500?
The Fusion 500 is the better choice if you value training variety and functional movement. Athletes, CrossFit enthusiasts, and anyone who wants to train movement patterns (not just isolate muscles) will appreciate the articulating functional arms. It's also the better pick if you're coming from a cable machine or functional trainer background and want those capabilities built into a multi-station gym.

Who Should Buy the Fusion 600?
The Fusion 600 is the better choice if your priority is heavy pressing movements with maximum muscle engagement. The bi-angular press arms provide a training experience that's closer to free weights than the Fusion 500's functional arms. If you're a bodybuilder or someone who focuses primarily on chest, shoulders, and back development through pressing and pulling movements, the 600 gives you a more intense contraction.
