100 A Day to B Strong Fitness Challenge: Day 9

Day 9 & we're feelin' FINE!


I love this core workout because we’re alternating back & forth from a slow, controlled movement that works our backside of our core, to a quick, explosive movement that works the front side of our core. It’s the perfect HIIT combo when you’re looking to CRUSH your core!

Oh & don’t be fooled!! It’s lower impact than the past 2 days.. but boy does it burn!
