This 28-Day Plank Challenge Will Transform Your Core in 4 Weeks
This 28-day challenge is designed to help you progress the amount of time you are able to hold a plank by, yes, holding a standard plank—but also by using other plank-based moves. Switching things up will not only help keep you from getting bored, but it will help you unlock the power in your core. Plus, the circuits will raise your heart rate, get you sweating, and light those abs on fire!
Remember: The plank is a powerful exercise. Strengthening your core muscles can help with everything from stability to helping prevent back pain to sculpting that waistline.
