Sure, everyone wants sexy six-pack abs, but the core muscles are responsible for much more than a few appreciative looks at the beach.
The core (composed of the oft-mentioned abdominals as well as the side, back, pelvic, and glutei muscles) provides a muscular framework that protects internal organs, aids movement, and lends balance and stability to the whole body.
To get a strong core, it’s important to switch it up and keep the muscles guessing. Use the list below—broken down into bodyweight and gym equipment categories—to train the upper and lower abdominals, obliques, and work on deep core strength and stability (we termed this “stability” to keep it simple!). Mix and match the exercises to work on core strength, whether at the gym or working out at home.
