OBS-2016 Rotary Rorso Fitness

Seat and cushion

The seat adopts a comfortable soft cushion design, which can provide good support for trainers and reduce physical fatigue during training; the cushions on both sides can fix and protect the body during waist rotation training, ensuring that the training movements are standardized and safe.

Auxiliary handle

The auxiliary handle on the right side of the equipment is convenient for trainers to hold when performing waist rotation training, which helps maintain body balance and makes training movements more stable and controllable.

Weight system

Located on the left side of the equipment, through adjustable weight blocks, it can meet the different resistance requirements of different trainers and help realize the personalized setting of the intensity of waist rotation training.

Main frame

It is made of solid metal, providing stable and reliable support for the entire equipment. It can withstand large training loads and ensure safety during use.

Core Function & Training Benefits

At its core, the OBS-2016 Rotary Rorso is engineered for controlled rotational movements, making it a standout tool for building core strength and overall functional fitness. It specifically engages:

Core muscles: Abdominals, obliques, and lower back (critical for stability and posture)

Glutes and legs: Supports lower-body strength development

Balance & coordination: Its smooth rotational mechanism enables precise, controlled twists, helping trainers improve body control and movement efficiency over time.

FAQ 

Q: Do I need professional help to assemble the OBS-2016 Rotary Rorso Fitness?

  A: Professional assistance is recommended but not mandatory. The product comes with a detailed, step-by-step assembly manual and all necessary tools (e.g., wrenches, screws). For users with limited assembly experience, hiring a fitness equipment installer can ensure proper setup and avoid potential safety risks. Assembly typically takes 1–2 hours with two people.

Q: Is this machine suitable for beginners, or only for experienced fitness users?

  A:It is suitable for users of all fitness levels. The adjustable weight system (starting from 5kg increments up to 70kg total) allows beginners to start with low resistance and gradually increase intensity as strength improves. For rehabilitation purposes (e.g., post-back injury recovery), it is also safe when used under the guidance of a physical therapist, thanks to its controlled rotational movements.

Q: How often should I maintain the OBS-2016, and what maintenance steps are required?

Routine maintenance is recommended every 3–6 months to ensure optimal performance:

• Wipe the seat cushion and handle with a mild disinfectant cloth after each use to prevent bacteria buildup.

• Check the main frame and weight stack connections for loose bolts; tighten them if needed.

• Lubricate the rotational mechanism (as indicated in the manual) with a silicone-based lubricant to keep movements smooth.

• Avoid placing heavy objects on the side cushions to prevent deformation.

Q: What space is required to place the OBS-2016 in a home gym?

  A: The machine itself measures 1100×1030×1620mm (L×W×H). For safe use, we recommend leaving an additional 500mm of clearance on all sides to allow full rotational movements without obstruction. This means a minimum dedicated space of 1600×1530mm (L×W) is needed—suitable for most standard home gym corners or spare rooms.

Q: What does the 1-year warranty cover, and what is excluded?

  A: The 1-year warranty covers manufacturing defects in mechanical components, including the main frame, weight stack, and rotational mechanism. It does not cover:

• Normal wear and tear (e.g., faded cushion fabric, minor scratches on the frame).

• Damage caused by improper assembly, overloading (exceeding the machine’s weight capacity), or accidental impact.

• Custom parts (e.g., personalized logos or non-standard colors) unless the defect is due to manufacturing errors.
