Hollow-body abduction

The hollow-body abduction is an isometric core exercise that includes leg abductions for an added challenge to the core and abductors. It targets multiple muscles of the core, but particularly the rectus abdominis or "six-pack" muscles. It can be performed for time or reps in the ab-focused portion of any workout.
