Leg Extension Machine (Leg Extension) SM126 – outdoor unit for 2 users, outdoor gym

SM126 is a durable leg extension machine designed for use in public spaces and recreational areas. The two-station design enables partners to train simultaneously, and the ergonomic arrangement of seats and rollers supports proper knee joint mechanics. Regular leg extensions strengthen the quadriceps, improve knee stability and help prevent injuries during sports activities. The unit is engineered for outdoor installation so you can train in the fresh air.

The SM126 is built on proven solutions and four key principles: effectiveness, ease of use, safety, and reliability.

Applications

Recommended for installation in parks, residential areas, near outdoor gyms, on school and university campuses, at holiday resorts, and in recovery zones at sports facilities.

Key benefits

• Quadriceps strengthening — targeted loading of the anterior thigh for better knee stabilisation.
• 2 stations — simultaneous training for two users increases zone throughput.
• Outdoor & durability — steel frame, powder coating, weather-resistant.
• Safety — stable chassis, comfortable seats and rollers, limited possibility of unauthorised disassembly.
• Simple operation — no load adjustment; lever biomechanics provide resistance without weight stacks.
• Low maintenance — easy to clean, built for intensive public use.

How to exercise on the SM126

1. Setup: sit deep and rest your back against the backrest. The knee’s axis of rotation should align with the machine arm’s axis. Place your feet under the roller above the instep.
2. Leg extension: engage the thigh muscles and brace the torso. Extend the legs to nearly full range (avoid hyperextension), then return slowly to the start position. Perform 3–4 sets of 8–15 reps.
3. Tempo & breathing: lifting ~1–2 s, lowering ~2–3 s; exhale during extension.

Tip: keep knees aligned with feet; don’t “throw” the weight with your torso. If you feel knee discomfort, reduce the range of motion.

Construction features

• Steel structure — profiles and tubes ensuring rigidity and stability.
• Powder-coated finish — protection against corrosion, UV radiation and impacts.
• Outdoor design — adapted for permanent installation on a foundation.
• Ergonomics — contoured seats, rollers over the instep and grips for added stability.
• Maintenance-free resistance — lever mechanism without load adjustment.

Technical specifications

FAQ – frequently asked questions

Which muscles work on the SM126?

Mainly the quadriceps (front of the thigh), and to a lesser extent the muscles stabilising the knee and hip.

Does the SM126 have load adjustment?

No. Resistance is generated by the lever design and bodyweight, which simplifies use and increases safety.

Can two people use the unit at the same time?

Yes. The SM126 has 2 stations, which helps reduce queues in the training area.

Is the equipment suitable for outdoor use?

Yes. The steel construction and powder coating ensure weather resistance with proper installation.

How do I care for the unit?

Clean surfaces with a soft cloth and a mild agent. Avoid sharp tools and aggressive chemicals.
