QF-G809 Back Extension

The QF-G809 Back Extension is a seated station built around a fixed hip pivot. A pad across the upper back and a leg roller hold the user in position while an 80 kg weight stack in the tower beside the seat supplies resistance, so no plate handling is needed. The machine measures 1365 x 1010 x 1460 mm and weighs 220 kg net. Frame and upholstery colours are customized to order, and the unit is CE and ISO9001 certified and packed in a wooden box.
