You’ve probably tried the cable woodchop in the past, but doing it in a half-kneeling position challenges your stability that much more, working your core in order to resist both rotation and lateral movement.

Training your core to stabilize your trunk while your limbs are in motion has more carryover to sports than crunches do.

How To Do It:

Kneel on one knee and grasp a rope handle attached to a pulley over your opposite shoulder. Brace your abs. Slowly draw the cable diagonally down and across your body to the outside of your left hip.

Quick Tips:

Don’t twist your body or crunch forward to complete the rep.

Perform three sets of 8–10 reps either at the beginning of your workout (if your core is a big weak point) or at the end.
