If you can challenge yourself to add 10 minutes of core work to your daily routine , you'd be surprised how it can change your body and mindset, Rogers says. That's why she's created the following 30-day ab workout challenge full of unique, dance- and Pilates-based ab exercises. The routine goes well beyond just planks and crunches, because the goal is to incorporate the entire core. "I wanted to keep the body moving which will help keep the mind active and present," she says. "You may even feel muscle groups you didn't know you had."
