Commercial Ab Crunch Machine MF-AC200
The MF-AC200 Commercial Ab Crunch Machine isolates the rectus abdominis and obliques through a biomechanically optimized crunch arc. Unlike floor crunches that strain the neck and lower back, the MF-AC200’s contoured back pad and adjustable range-of-motion stops let you train abs safely through a full stretch-to-contraction range. Features a 150 lb selectorized weight stack with 10 lb increments, oversized grip handles, and an adjustable seat that accommodates users from 4’10” to 6’6″. The pivoting arm tracks the natural spinal flexion curve, maximizing abdominal activation while minimizing hip flexor involvement.
