Shock Leg Extension Machine

In brief — Shock Leg Extension Machine: weight 148 kg, material rubber, price on quotation.

The Shock Leg Extension isolates the quadriceps — rectus femoris, vastus lateralis, vastus medialis and vastus intermedius — on a frame built for commercial duty. Strengthening the front of the thigh is not only an aesthetic goal: the quadriceps drive running, jumping, climbing and simply standing up, and they take heavy demand in rugby, football and cycling. This machine gives gyms, clubs and performance centres a safe, guided way to train and rehabilitate them.

Built for intensive club use

• Main frames in rectangular and oval steel tube for rigidity and long service life.
• Seat and backrest in thick high-density foam, upholstered in flame-retardant, antibacterial Skai for safe, hygienic daily use.
• Fully anatomical backrest that sets correct posture and reduces injury risk during the exercise.
• Plate-holder bars in stainless steel; self-lubricating joints that require no maintenance.
• Neoprene grips for secure hand placement through the working set.
• Designed in compliance with UNE-EN ISO 20957-1, 20957-2 and 20957-4.

Technical specifications

Frequently asked questions

Is this machine suitable for rehabilitation work?

Yes — the guided single-joint movement and anatomical backrest make it a standard tool for controlled quadriceps loading, with the working weight set precisely by the plates fitted.

What maintenance does it need?

Very little: the joints are self-lubricating, so routine care is limited to upholstery cleaning and periodic checks of fixings.

Which plates does it take?

Standard Olympic-format discs on stainless steel horns; we confirm compatibility with your existing plates during quotation. See the full Shock strength range and our other plate-loaded machines.
