How to do a plank:

Starting position: Begin on your stomach, lying face down with your forearms on the floor. 

Body alignment: Ensure your elbows are directly under your shoulders, legs extended, and feet together or shoulder-width apart. 

Body lift: Push up into a straight line, raising your torso off the floor while maintaining a neutral spine. 

Core engagement: Engage your abdominal muscles by pulling your belly button towards your spine. 

Holding the plank: Hold the position for a set time, aiming for 30 seconds initially. 

Breathing: Breathe steadily and deeply throughout the exercise. 

Lowering: Lower your body back down to the starting position and rest.
