A strong core is essential for any athlete and CrossFit core and abs workouts are a great way to achieve this result.
CrossFit always puts function first, unlike bodybuilding for example, which generally prioritises aesthetics over fitness. The former is a healthy approach, because your body becomes defined by what it can do, and not just by how it looks.

In the end it all comes down to what you are training for, and what goals you would like to reach. Whatever your targets, these CrossFit workouts will help you to forge a strong core and six pack abs. Remember that without the right nutrition, you will not see or experience any meaningful results.

Abs Workouts Scaling Options
This WOD is meant to be relatively short—most athletes should finish “Annie” in 10 minutes or less. The repetitions should be fast and mostly unbroken.
If big, unbroken sets of Double-Unders aren’t available to you yet, sub them for Single-Unders. If big, unbroken sets of sit-ups aren’t available to you yet, reduce the volume.
When it comes to scaling movement, prioritize range of motion: Scale the first set of 50 sit-ups, for example, by dropping the volume to 25 perfect, full range of motion reps. 50 Crunches or half Sit-Ups aren’t nearly as beneficial as the full range of motion full Sit-Up.
Intermediate
30-25-20-15-10
Double-Unders
Sit-Ups
Beginner
30-25-20-15-10
