We've got a fun two parter core workout today. Part 1 is a 5 minute plank! Yes, 5 minutes. The countdown clock will start at 5 and your goal is to hold a plank. However, every time you break, it's a 10 sit-up penalty, then back to planking in that 5 minute window.

After a three minute rest, we've got 5 rounds alternating between bird dogs and dead bugs, 30 seconds each movement. Keep these slow and controlled, your body tight the entire time.
