Performing the: A Step-by-Step Tutorial Mountain Climber Lunge
Drive your right knee towards your chest, as if you're climbing a mountain, while keeping your core engaged and your hips down.
Now, extend your right leg back and place it on the ground, then bring your left foot forward, next to your left hand, transitioning into a lunge position.
Push off your left foot and return it back to the starting plank position.
Repeat the process with the left knee driving towards the chest and transitioning into a lunge with the right foot forward. Continue alternating sides for the desired number of repetitions.
