Abdominal Crunch Machine

A selectorized abdominal crunch machine built for strict guided ab work — the supported seated position locks the lower body in place so the abs do all the work through every rep. The trainee sits with feet hooked under the front foot rollers, shoulders pressed into the dual overhead shoulder pads, and grips the curved handles overhead, then crunches the upper body forward against the resistance. The supported position eliminates lower-back strain that plagues unsupported sit-ups and forces clean rectus abdominis activation through the full range. The selectorized weight stack indexes from light loads through serious working weight in single-pin increments, letting trainees scale ab load like any other major lift; chrome guide rods keep the cable run smooth through years of high-traffic use. Heavy welded frame with bolt-down footplates plants the machine flat to the floor under aggressive use. Built for serious commercial gyms, performance centres, and studios that want to load core work the same way they load every other body part — sets, reps, and progressive overload, not just bodyweight crunches on the floor.
