Product Information
The SportsArt DF-306 Performance Lower Back/Ab Crunch combines abdominal-crunch and back-extension
movements in a commercial dual-function push-pull station.
A fully adjustable chest and back pad, multiple foot supports, and range-limiting adjustments establish

DirectDrive opposing cams reduce cable slack and speed exercise changeover while providing equal
7.7-pound starting resistance for each movement.
A 220-pound selectorized stack, supported contact points, and durable facility-focused construction
enable controlled abdominal and lower-back strengthening.

Abdominal crunch and back-extension movements share one push-pull station for complementary core and lower-back training.

Frequently Asked Questions

How should the foot supports be used?
Choose the support that keeps both feet stable and helps maintain controlled alignment throughout the movement.
How is the movement range limited?
Set the range adjustment before exercise to establish a comfortable start and stop position for the selected movement.
