#1 – Weighted Crunch

The weighted crunch uses a weight plate to work your abs. You can perform this exercise by holding the plate on your chest while you move into crunch mode, or you can lift it above your head instead. Either way will get the job done, but the following video demonstrates the latter:

#2 – Swiss Ball Crunch

In a swiss ball crunch, you do a crunch on a fitness ball. Not only are you focused on crunching, but you also have to stabilize yourself on the ball, which contracts your abs from all angles.

#3 – Weighted Swiss Ball Crunch

To kick things into extra-high gear, you can combine this exercise with the previous one for a weighted swiss ball crunch. You can hold a weight plate, dumbbell, or medicine ball — it doesn’t matter, as long as you carry some extra pounds. We guarantee you’ll feel this one the next morning!

#4 – Decline Crunch

For the decline crunch, you’ll need access to a decline bench. Lying down at a decline will create more resistance as you propel your upper body into the crunch position. For each rep, be sure not to touch your shoulders all the way down.

#5 – Cable Crunch

Using resistance from a gym’s weighted cable machine, the cable crunch will give you some deep ab work. Be careful to position your neck, back, and hips just right, so as not to cause any unwanted strain!

#6 – Oblique Crunch

When working the core, it’s important not to forget your obliques, which are the muscles located on either side of your abs. Round out your ab workouts with the oblique crunch, remembering to switch sides so that both your right and left obliques get equal attention.
