5057 Hammer 5000 Series Plate-Loaded Back Extension / Abdominal & Oblique Machine

The 5057​ is a commercial-grade, plate-loaded rear delt/back extension and abdominal machine designed for serious core development. Featuring a robust silver steel frame and a professional black upholstery finish, it delivers the durability and biomechanical precision demanded by high-traffic facilities. The angled chest pad, adjustable seat, and secure leg rollers provide maximum stability, allowing users to isolate the lower back, glutes, and abdominal muscles effectively. The dual vertical handles and rear plate-loading post accommodate progressive overload for both hyperextensions and controlled crunch movements.

Frequently Asked Questions

Q: What exercises can the 5057 perform?

A: The 5057 is designed primarily for prone back extensions (hyperextensions) to target the erector spinae, glutes, and hamstrings. By adjusting the chest pad and user positioning, it also supports abdominal crunches and oblique twists, making it a versatile dual-function core machine.

Q: What barbells or weight plates does it fit?

A: The 5057 features a standard 50mm (2-inch) Olympic-sized plate-loading horn located at the rear of the frame. It perfectly fits standard Olympic bumper plates (like our 007 Shield PU Bumper Plates​ or 016 Tri-Grip Rubber Plates) and Olympic weight trees.

Q: Is it suitable for commercial gyms?

A: Absolutely. The heavy-gauge steel frame and commercial-grade padding are built to withstand the rigors of high-volume training environments, including box fitness centers, boutique studios, and themed training facilities.

Q: How should the 5057 be maintained?

A: Wipe the upholstery and frame with a damp microfiber cloth and a mild, pH-neutral cleaner to remove sweat and oils. Avoid harsh chemical solvents that could degrade the padding. Periodically check all bolts, adjustment pins, and the plate-loading horn to ensure structural integrity. Store away from excessive moisture.

Q: Can it be dropped or slammed?

A: While the steel frame is highly durable, we advise against dropping heavy plates directly onto the machine or slamming the weight stack. Controlled movements are essential to preserve the coating, welding, and central pivot points. Always use rubber flooring.
