Overview
A Roman chair style hyperextension bench with adjustable padded leg holders, a padded seat and handles, and a powder-coated steel tube frame. Built for back extensions, glute and hamstring work, and ab training at home.
- Adjustable two-part padded leg holders
- Hyperextension and ab dual-use design
- Powder-coated heavy-duty steel tube frame
- Compact footprint for corner storage
Who it's for
Home-gym users who want a compact station for back extensions and core work. Shorter or taller users may need to adjust the leg-post position, since reviewers near 5'10 to 6' found the stock fit sized for them.
What buyers say
From Amazon customer reviews.
Reviewers repeatedly called the frame sturdy for the price and liked how compactly it stores, but several flagged the welded handlebars flexing under load, and more than one reported loose hardware or a banged-up shipping box on arrival.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sturdy heavy-duty frame that doesn't sway
- Padded legs and seat for comfort
- Folds into small footprint for storage
- Works both hyperextension and ab exercises
- Welded handlebars flex noticeably under weight
- Hardware can arrive loose in box
- Assembly takes time and careful steps
- Padding runs firm on some units
Performance notes
The leg-pad post and seat angle set your range of motion, and reviewers describe getting a full 90-degree hang for experienced users, though very short or tall bodies may need to move the post position.
