For most mere mortals, abs exercises using just your bodyweight, like sit-ups and leg raises, provide enough of a challenge to encourage muscle growth and increase strength. But some, especially those looking to take their six-pack to the next level, might need to recruit additional load to keep them growing.
Enter the cable crunch. This bodybuilding favorite uses the cable machine to make the crunch exercise much more challenging. That may sound great, but it’s not the easiest movement to master and you should exercise caution before adding it to your abs workouts.
