Overview
A foldable 45-degree hyperextension bench with adjustable height and back settings and a split pad design, rated to 330 lbs for glute, hamstring, lower back and ab training at home.
- 330 lb weight capacity with tip-resistant base
- Adjustable height and back for different body sizes
- Split pad design with non-slip handlebars
- Folds for storage in small home gyms
Who it's for
Home gym users doing hyperextensions, sit-ups and lower-back rehab work in a compact, foldable footprint. Anyone well over the 330 lb rating or notably taller than 5'8 should look at a full-size bench instead.
What buyers say
From Amazon customer reviews.
Several buyers called it good value and easy to assemble, including one using it for lower-back rehab who found it lightweight and easy to store. Others were less satisfied: one flagged the materials and price as mismatched, and another received parts with sub-par fit and finish on the upholstery.
Strengths and trade-offs
Drawn from this product's published specifications.
- Folds flat for storage between uses
- Straightforward solo assembly for most buyers
- Adjustable height and back settings
- Included wrenches are thin and awkward to use
- Upholstery fit and finish inconsistent between units
- A few buyers received missing or defective parts
Performance notes
The split pad and adjustable back let it target hyperextensions, twists and sit-ups, with non-slip handlebars and stabilizers meant to keep the frame steady during reps. One reviewer used it specifically for lower-back rehab and found it held up to regular use.
