The plank is a simple exercise that can be done anywhere, anytime.
It targets multiple muscle groups, including the core, arms, and legs.
The plank also helps improve posture and balance.
To perform a plank, start in a push-up position and hold your body in a straight line for as long as possible.
As you get stronger, you can increase the duration of the plank or try different variations, such as side planks or plank jacks.
