Performing the: A Step-by-Step Tutorial Power Point Plank
Engage your core and maintain a straight line from your head to your heels, ensuring your hips are not sagging or raised too high.
Now, lift your right arm and extend it straight out in front of you, pointing like you're using a laser pointer, while maintaining the plank position with the rest of your body.
Hold this position for a few seconds, then lower your arm back to the starting position.
Repeat this motion with your left arm, and continue alternating arms for the desired number of reps.
