Description
Building a stronger core has never been easier thanks to a Keystone Ab / Low Back that will fit your commercial fitness facility as well as it fits everyone you serve. From precise body positioning geometry to moisture-resistant cushioning to welded-steel frames, we designed every detail for performance, comfort and durability in tough, high-traffic fitness environments.
Natural Biomechanics
An adjustable design offers seven starting positions to give users of all sizes a comfortable range of motion, a large roller pad moves with the user for comfortable and smooth reps, a refined cam design keeps resistance consistent in both directions, and a large orange pivot point indicator optimizes the alignment of the hips.
Comfort & Moisture-Resistance
The ergonomically sculpted cushions make even hard sets comfortable, while moisture-resistant materials keep the cushions looking and feeling like new through years of demanding workouts.
Lasting Durability
Thoughtful Design
All our selectorized stations feature a low stack height for clean, open sight lines, plus space-saving back-to-back configurations, easily accessible open frames, non-slip storage shelf and device cradle.
Stability & Security
The angled seat and lumbar pads provide excellent support through every rep, while the dual non-slip foot platforms provide support and stability for users of all sizes.
