Power Line Prone Leg Curl - 100 kg Weight Stack

The Power Line Prone Leg Curl is a selectorised hamstring station with a 100 kg weight stack. It measures 1120 x 1750 x 1655 mm and weighs 200 kg. The face-down position holds the pelvis against the pad, so the hamstrings work as knee flexors with no hip contribution. Professional price: 2,550 EUR excluding VAT.

Why the prone position matters

Lying face down fixes the hip in extension. That removes the pelvic tilt a seated or standing curl allows, and it is the reason the prone format remains the reference hamstring exercise in physical preparation and in return-to-play work after knee or hamstring injury. What the stack shows is what the hamstrings actually produced.

• Selectorised 100 kg weight stack
• Adjustable ankle roller to match limb length
• Contoured bench holding the pelvis and supporting the trunk
• Handles at the front for stabilisation under load
• Steel weight plates insulated with noise-reducing PVC
• PVC-coated steel cable on high-strength nylon pulleys
• PU foam padding with synthetic leather

Muscles worked

Primary load on the hamstring group: biceps femoris, semitendinosus and semimembranosus. The gastrocnemius assists through the knee, and the degree of ankle dorsiflexion adjusts how much. The station complements a leg extension directly, and a lower-body zone with one but not the other trains the quadriceps and hamstrings out of balance.

Set-up

Position the ankle roller just above the heel, not on the achilles tendon, and align the knee with the pivot of the machine at the edge of the bench. Keep the hips in contact with the pad throughout: lifting them is the standard compensation and it tells you the load is too high.

Frequently asked questions

Prone or seated leg curl?

Both load the hamstrings, but at different hip angles, so they are not interchangeable. The prone version isolates knee flexion with the hip extended and is the closer match to sprinting mechanics. A floor equipping only one hamstring station usually chooses prone; a floor with two should have both.

Is it suitable for rehabilitation use?

Yes, with supervision. The 100 kg stack allows very light increments at the bottom of the range, and the fixed prone position removes the compensations a physiotherapist would otherwise have to correct manually.

How much floor space is required?

The machine occupies 1120 x 1750 mm. Allow clear space behind for the stack and enough room at the foot end for the roller to travel. At 200 kg, verify the slab capacity on upper floors.
