We know that there’s no great magic to achieving the perfect 6 pack, but rather it’s about a lot of hard work and clean eating. We also know that no matter how badly we’d like to believe otherwise, there’s no such thing as spot training.
This doesn’t mean, however, that you shouldn’t be working out your abdominal muscles on a regular basis. They make up a very significant part of your core and if they aren’t engaging then you are doing yourself a big disservice.
Although a classic, you’ve probably heard by now that crunches aren’t the most effective abdominal workout. The reason for this is because they work only the front and sides of your body. To get a better, more “total” and functional workout you should be focusing on working out the entire core. That being said, including some crunches in your workout is not a bad thing in a pinch, but there are so many better exercises out there.
