What is what does planking means?

Planking is an activity where a person lies flat on their stomach with their arms and legs straight and stiff like a board. The idea is to hold this position for as long as possible, often in unusual or amusing locations as a sort of challenge or dare. Planking became popular through social media in the early 2010s and has since expanded into a broader trend of balancing and bodyweight fitness activities. Planking can improve core strength, stability, and balance. However, it can also be dangerous if done on unstable surfaces or for too long, leading to strain or injury.
