Overview
Built from steel tubing and rated to a 300 lb user capacity, the Cap Strength Roman Chair is a back extension bench for home gyms, with adjustable pads and footrests to fit different body sizes.
This is a single-purpose machine, not a multi-station bench, so weigh that against the space and money before buying. CAP Barbell has built strength equipment for decades, and the steel-tube construction here matches that pedigree, but there's no seller-listed footprint dimension, so measure your space against your other gym gear before ordering.
- 300 lb rated steel frame
- Adjustable pads and footrests
- Targets abs, obliques, lower back and glutes
- Compact design for home gyms
Who it's for
Home gym owners who want a focused station for back extensions, core work and glute training, especially in a space too small for a full bench and rack setup. Not suited to anyone over the 300 lb rated capacity.
