You know we heart interval training, and that’s especially true when it comes to core. Rather than focusing on reps, we harness the power of our abs for a gut-wrenching, heart-pounding period of time … and then give our muscles some time to recover before we go right back at it. This week is no exception. Build your core strength and resilience with timed planks, power sit-ups and pop jacks. You’ll have plenty of time to recover later, we promise.
