The plank is one of the simplest tests of core strength and endurance. Time your hold and see how you rate.
How this works
Hold a forearm plank with elbows under your shoulders and a straight line from head to heels. Stop when you can no longer hold good form. Ratings are a general guide for healthy adults rather than a clinical norm.
Results are estimates for general information only and are not medical advice. Talk to your doctor or a registered dietitian before making major changes to your diet or exercise, especially if you are pregnant or have a health condition.
