The PPF-K545 turns the classic hyperextension into a loadable exercise: users hinge at the hips over the pads and extend against a plate-loaded lever. It trains the spinal erectors, glutes and hamstrings with progressive resistance instead of body weight alone.
Design & features
- Hip pads on an adjustable bracket with hole-plate adjustment
- Handles beside the hip pads and ankle rollers
- Slotted steel foot platform
- Long lever arm with chrome weight horn
- Storage horns to keep plates at hand
Ideal for
Commercial gyms, personal training studios and serious home gyms looking for plate-loaded strength work without a weight stack. It fits naturally next to a free-weight area, where plates are already on hand.
