Performing the: A Step-by-Step Tutorial Mountain Climber
Lift your right foot off the ground and draw your right knee towards your chest, keeping your toes off the ground.
Return your right foot back to the starting position.
Now, repeat the same movement with your left foot, bringing your left knee towards your chest and then returning it back to the starting position.
Continue alternating between your right and left foot, increasing your speed as you get more comfortable with the movement, simulating a running motion while maintaining the plank position.
