Overview
The ZELUS Ab Crunch Coaster is a foldable home gym bench built around two curved, independently moving tracks that let each leg drive a knee raise on its own. A locking incline offers 4 angles, and a digital display counts time, reps, and estimated calories during a session.
Built from powder-coated heavy-gauge steel with a stated 330-pound user capacity, the frame is meant for repeated use rather than occasional storage only. The dual-track design combines a seated ab crunch with a hanging-leg-raise style motion, working the knees independently instead of on a single fixed pivot.
- Dual independent-track ab crunch design
- 4-level locking incline
- Digital time, rep and calorie display
- Rated to 330 lb user weight, folds for storage
Who it's for
Fits anyone assembling a small home gym who wants a dedicated ab station that folds away between sessions. It's a bodyweight machine, not a weighted one, so lifters chasing progressive resistance for their core will outgrow the 4 fixed incline settings.
What buyers say
From Amazon customer reviews.
Most buyers describe assembly as quick, often 15 to 30 minutes, though one noted the printed instructions skip clear steps and they had to work out the pin placement by trial and error. The curved track design gets specific praise for feeling more natural than straight-bar crunch machines, and several reviewers call the build sturdy across different body sizes. One reviewer who trained on it daily for a month at a steep angle said they saw no visible difference in results, despite finding the machine well built.
Strengths and trade-offs
Drawn from this product's published specifications.
- Independent left and right knee tracks for targeted movement
- 4 locking incline levels from gentle to steep
- Digital display tracks time, reps and calories per session
- Folds down for storage between workouts
- Fixed incline levels cap how much resistance can be added
- Assembly instructions are reportedly unclear, per one buyer
- Foam padding and plastic components may wear over time
Performance notes
The curved dual tracks let each knee move on its own path rather than a single locked pivot, which is the machine's main departure from a standard crunch bench. Resistance comes entirely from body weight and the 4 locked incline positions rather than added plates, so intensity is set by angle and rep count. One reviewer who trained daily for a month at the steepest angle reported no noticeable strength change, pointing to a resistance ceiling that's angle-limited rather than load-limited.
