FS-57 Low Back/Abdominal
Brand: TRUE Fitness · Category: Pin Loaded
The TRUE FS-57 Low Back/Abdominal is a commercial dual-function back extension and abdominal crunch from TRUE’s Fitness Line series, built for gyms that want a core pair on one compact seat. A five-position range-of-motion adjustment switches easily between the low-back extension and the abdominal crunch, and dual non-slip foot positions support a wide range of users. It carries a 77 kg (170 lb) weight stack as standard (113 kg (250 lb) heavy stack optional) and occupies 112 × 125 cm of floor.

Dual non-slip foot positions
77 kg stack, 113 kg optional
Compact 112 × 125 cm footprint
The TRUE FS-57 is the low back and abdominal machine in TRUE Fitness’s Fitness Line, letting users change easily between back extension and abdominal crunch exercises. A five-position range-of-motion adjustment makes the switch, and dual non-slip foot positions accommodate a wide range of users while supporting them during exercise.
Who is this machine for?
The FS-57 suits commercial gyms, hotel and corporate fitness centres, physiotherapy settings and premium home gyms in India that want the front and back of the core trained on a 112 × 125 cm footprint. The weight stack ships at 77 kg with a 113 kg heavy stack available.
Exercises it supports
The crunch targets the rectus abdominis with the obliques assisting; the back extension targets the erector spinae with the glutes and hamstrings assisting. Training both builds a balanced trunk that supports every other lift and improves posture.
Build quality and adjustment
The range adjustment has five positions that set the start for either exercise, the foot positions are dual and non-slip, and the pads support the torso in both movements. The machine weighs 201 kg with the standard stack and 237 kg with the heavy stack.
Like every Fitness Line machine, it is TRUE’s compact, commercial-grade selectorised design for high-use environments: matte-black frame with custom frame and upholstery colours, an instructional placard with a QR code linking to a setup video, and clearly marked adjustments. TRUE backs the frame for 10 years with 5 years on parts and 1 year on cables, linear bearings and labour.
Space and installation
The FS-57 measures 112 × 125 × 145 cm (44" × 49" × 57") (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, grips and shroud after each session. Check the cables, pulleys and pivots 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.
