Crush Your Core and Shock Your Body Into Growing a Well Defined Six-Pack

To force your abs into becoming more defined you need to make them work harder for longer so that you fatigue as many muscle fibers as possible. That’s because it’s the accumulated damage from a testing session that will instruct your body to grow back your abs muscles bigger, stronger, and more defined.

This five-move session does just that by placing lots of tension on your entire core, so it never has the chance to switch off during a rep. Follow the workout guide carefully, focusing on keeping your core tight and engaged from the beginning of the first set to the end of the last.

This superset works your core and lower abs especially hard as you move your legs upwards, downwards, left and right. Keep each rep quite fast but always controlled so it’s your muscles that do the work, not just your legs swinging back and forth.

1A. Hanging knee raise:

Sets 4 Reps 15 Rest 30sec

  • Hold this position for a one-count, then lower back to the start.
  • That’s one rep.


1B. Hanging knee twist:

Sets 4 Reps 15 each side Rest 60sec
