This Abs Challenge Will Transform Your Core

Time to work some midsection magic: Our 4-week abs challenge is your blueprint to a core that performs as good as it looks (not to mention helping with better posture and less back pain!).

Each day, we’ll do a different ab exercise designed to target every angle of your core, from the deep transverse abdominis to the obliques. You’ll push through planks, twist through Russian twists, and crunch your way to a stronger, more sculpted core.

“Your abdominal and core muscles are involved in many different movements and actions where they work in isolation [alone] or synergistically [together] at varied levels of intensities,” says Ben Lauder-Dykes, CPT, personal trainer, Fhitting Room instructor, and the host of our June Movement of the Month Club.

“So it’s important to expose yourself to different exercises so you can build strength and competency to perform well in your workouts or [daily] activities.”

Lauder-Dykes’ program will help you build the kind of core strength that stabilizes your entire body, improves your balance, and reduces the risk of injuries. So grab a mat and prepare to commit just a few minutes a day to transform your core!

Join us to get all the benefits of a strong core

Strong abs are important not only for your workouts but also for everyday activities. Here is just a sampling of the benefits of a strong core.

Strengthening the core muscles stabilizes the spine, pelvis, and shoulder girdle, creating a solid base of support; this allows for greater efficiency of movement and decreases the chance of injury, according to a 2015 review in the Brazilian Journal of Physical Therapy.

A stable core is also linked to improved balance, which supports functional abilities and reduces the risk of falls, especially among older adults, per a 2014 study in the Journal of Physical Therapy Studies.

Additionally, a powerful core enhances posture and can alleviate lower back pain, a common issue for many adults, according to a 2015 study also in the Journal of Physical Therapy Studies.
