The core (aka ABS) is made of three different muscle groups:
To have a strong (and sexy!) core isn’t determined by how many crunches or hanging leg lifts you can do. The main purpose of the core is to stabilize the torso and if power during movement. One of the best exercises to build core strength is a simple, front-weighted squat. When performing a squat properly, all three areas of the core have to work in order for the squat to be effective. Another great core exercise is a plank. Planks build the endurance of midsection stabilizers.
Solely doing an exercise like crunches to attempt core strengthening does, for the most part, nothing. The core has three different muscles groups with a total of six muscles in the midsection alone. So to build that sexy and strong core, you need to perform exercises that work all six muscles during the same movement. In other words, there’s no more lying down on your back to do crunches. Get up! It’s time to start running, pushing, pulling, twisting, squatting, bending, and lunging all for “NON-SITTING POSITIONS.”
It’s time to train smarter and to train your body the way it was intended to move. Your body was built to move in multiple planes, not one-dimensionally. Stop training that way. Salute your core by training it smarter. So when you are ready to peel off that shirt, not only do you have a sexy midsection but you also have a functional core as well.
