The CORTEX® SM25 Multi Gym is a comprehensive fitness machine designed for a variety of strength training exercises, combining a dual stack functional trainer, Smith machine, and half rack into a single unit. This versatile equipment is suitable for users looking to perform a wide range of exercises in a compact footprint.

Function Description:

The SM25 Multi Gym offers three primary functions:

Dual Stack Functional Trainer: This feature allows for independent cable exercises from two separate weight stacks, enabling users to perform movements that target various muscle groups with constant tension. The adjustable pulley system provides flexibility in exercise selection and range of motion, making it ideal for functional training, rehabilitation, and sports-specific movements.
Smith Machine: The integrated Smith machine provides a guided barbell path, offering enhanced safety and stability during heavy lifts such as squats, bench presses, and shoulder presses. The fixed plane of motion helps users focus on muscle engagement and form, making it suitable for both beginners and experienced lifters. Safety catches are typically included to prevent injury in case of muscle failure.
Half Rack: The half rack component allows for free weight exercises with an unguided barbell. It typically includes J-hooks for racking the barbell and safety spotter arms to protect the user during exercises like squats, overhead presses, and deadlifts. This feature caters to users who prefer the natural movement and greater muscle activation associated with free weight training.

Important Technical Specifications:

While specific dimensions and weight stack capacities are not explicitly detailed in the provided pages, the manual indicates a maximum user weight of 100kg. The assembly instructions reveal various bolt and washer sizes, including M10 x 70mm, M10 x 95mm, M10 x 90mm, M10 x 15mm, M8 x 35mm, M8 x 80mm, and M8 x 16mm, along with corresponding washers (Φ10, Φ8, M10). These specifications suggest a robust construction designed to withstand significant loads during exercise. The presence of multiple weight stacks (implied by "dual stack functional trainer" and illustrated in assembly steps) indicates a substantial resistance range for various exercises. The machine's design incorporates numerous pulleys and wire ropes, which are critical components for the functional trainer aspect, requiring regular inspection and maintenance.

Usage Features:

The SM25 Multi Gym is designed for comprehensive full-body workouts. Key usage features include:

Versatility: The combination of a functional trainer, Smith machine, and half rack allows for an extensive array of exercises, targeting all major muscle groups. This eliminates the need for multiple pieces of equipment, making it an efficient solution for home gyms or smaller fitness facilities.
Safety: The Smith machine's guided barbell and safety catches, along with the half rack's safety spotter arms, provide crucial safety mechanisms, especially when lifting heavy or training alone.
Adjustability: The functional trainer's adjustable pulleys enable users to customize the height and angle of resistance, accommodating different body types and exercise variations.
Weight Selection: The weight stack system, likely with a pin-loaded mechanism, allows for quick and easy adjustment of resistance levels, facilitating progressive overload and efficient workout transitions.
Accessory Compatibility: The manual illustrates various attachments and components, suggesting compatibility with a range of accessories such as different handles, bars, and possibly a landmine attachment (part 45).

Maintenance Features:

The manual emphasizes the importance of regular maintenance to ensure the longevity and safe operation of the SM25 Multi Gym. Key maintenance features and recommendations include:

Lubrication: Moving joints should be lubricated with silicon spray periodically. The guide rods and weight plates require lubrication over time, even though the product is pre-lubricated from the factory.
Wire Rope Inspection: Pulley and wire ropes must be checked regularly for signs of wear. Any wear could pose a danger to the user. The tension of the wire rope should also be checked and adjusted regularly.
Hardware Inspection: All bolts and nuts need to be checked for tightness and re-tightened if loose.
Moving Parts Inspection: All moving parts should be regularly inspected for signs of wear or damage. If any damage is found, the device should be stopped immediately, and the after-sales service department contacted.
Weld Inspection: Welds should be checked for cracks.
Cleanliness: The machine can be kept clean by wiping it down with a dry cloth.
Attachment Security: All handle attachments must be fully secured before use to prevent injury.
Damage Prevention: Care should be taken not to damage plastic or metal parts with heavy or sharp objects.

Failure to perform routine maintenance may result in personal injury or equipment damage, highlighting the critical role of regular upkeep for the SM25 Multi Gym. The manual also advises that the product is subject to change without notice, and up-to-date manuals are available online. It is strongly recommended that assembly be performed by two or more people to avoid possible injury.
