Great Abs Exercises – 10 Sit Up Variations to Build a Solid Six Pack and Core

strong core is essential for any athlete, six pack abs are not – but they are fun. 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 8 sit up exercises 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.

Always keep your core training varied in order to continually test and improve your body. 

Add these variations into your training. 


  1. Lie on your back with your knees bent and pointed to the ceiling. Hold a weight at the center of your chest (but not resting on your chest).
  2. Curl up without letting your chin touch your chest. The weight might move forward (toward your midsection), but make sure that you’re holding it above you the entire time so that you feel the full weight.
  3. Lower back down with control.


Start with a 5-pound medicine ball or dumbbell and work up from there.


  1. Start on your back with your hips and knees bent at 90-degree angles. You shins should be parallel to the floor. Bring your hands behind your head
  2. Holding your legs in place, exhale and crunch up without letting your chin drop into your chest
  3. Inhale as you lower back down


For an added challenge, lift your butt off the ground as your head and shoulders come up — as long as you don’t rely on the momentum of the move to raise and lower.
