MLC400B Prone Leg Curl

Brand: Steelflex · Model: MLC400B · Category: Pin Loaded

The Steelflex MLC400B Prone Leg Curl is a full-commercial prone leg curl machine from Steelflex’s Mega Power series, built for commercial gyms that want a lying hamstring curl that protects the lower back. Pop-pin adjustment of the ankle rollers sets alignment and resistance, the chest and hip pads sit at divergent angles to safeguard the lower back, and lateral dipped handgrips keep the user stable. It carries a 97.5 kg (215 lb) weight stack as standard (143 kg (315 lb) or 189 kg (415 lb) optional), is rated for users up to 120 kg (264 lb) and occupies 176 × 95 cm of floor.

• Lying (prone) hamstring curl

• Pop-pin ankle roller adjustment

• Angled chest and hip pads protect the lower back

• 97.5 kg stack, 143 or 189 kg optional

• 120 kg maximum user weight

The Steelflex MLC400B is the prone leg curl in Steelflex’s Mega Power full-commercial line. The user lies face down, pop-pin adjustable ankle rollers set the alignment and the start of the curl, and the chest and hip pads are set at ergonomically divergent angles so the lower back stays safe while the hamstrings work. Lateral dipped handgrips give a stable hold.

Who is this machine for?

The MLC400B suits commercial gyms, hotel and corporate fitness centres, sports-conditioning rooms and premium home gyms in India that want a lying hamstring curl for lifters and athletes. Pairing it with the seated MLC400 covers both hip positions, and the 120 kg maximum user weight covers most users.

Muscles worked and key exercises

The prone leg curl targets the hamstrings with the hip extended, with the gastrocnemius assisting; this position emphasises the short head of the biceps femoris and suits sprinters and jumpers. The angled pads keep the hips down so the lower back does not arch under load.

Build quality and adjustment

Pop-pin adjustment on the ankle rollers sets alignment for different leg lengths, the chest and hip pads diverge to protect the lumbar spine, and the lateral handgrips keep the shoulders anchored. The flat-belt drive delivers a smooth curl across the full 97.5 kg stack.

Like every Mega Power machine, it is built on 50 × 150 mm oval steel tubing with a two-coat, electrostatically applied powder finish; 5 cm of rebonded foam under 15 mm of high-resilience foam with a CGPC PVC cold-latex cover, double stitched; dipped PVC handgrips; a flat-belt drive with a tensile strength above 2,280 kg; a 4 mm acrylic shroud; and noise-absorbing cushions under the weight stack. An instructional placard is fitted to every machine.

Space and installation

The MLC400B measures 176 × 95 × 167 cm (69" × 38" × 66") (L × W × H). Leave about 0.6 m of clear space on the user side for entry and exit and 0.5 m around the weight stack for pin changes. No power is needed. Luxe Fitness delivers, assembles and levels the machine and fits the weight stack on site.

Care and maintenance

Wipe the upholstery, handgrips and shroud after each session. Check the belt, pulleys and pivot bearings monthly, keep the guide rods clean and lightly lubricated as the manual directs, and tighten pad and handle fasteners. Book a service visit if the movement becomes rough or the stack catches on the guide rods.

Frequently asked questions

Is a prone leg curl hard on the lower back?

The MLC400B’s chest and hip pads are set at divergent angles precisely to keep the hips down and the lumbar spine neutral, which removes the strain a flat bench creates.

What is the difference between the Steelflex MLC400B and MLC400?

The MLC400B is the lying (prone) curl; the MLC400 is the seated curl. Both train the hamstrings; the seated version is easier for older members to use, the prone version suits athletes.

What warranty does the Steelflex MLC400B have in India?

Luxe Fitness offers up to 5 years warranty on this machine, covering frame, major moving parts and upholstery on separate terms. Ask us for the warranty card for your exact model before purchase.
