Mountain climbers are also known as running planks as they are performed in a plank position while your legs engage in a running-like movement. This exercise is not only good for building core strength but also acts as a cardiovascular activity. It is good for developing the abdominals, arms, shoulders, and quads.
To perform a mountain climber, first, begin in the plank position. This is down, facing the floor as you hold yourself up by your toes and your hands. Next, you bring one knee forward before switching legs. Continue switching legs so that you are effectively running against the floor.
A common mistake in this exercise is to let your weight shift back so that you are in less of a plank position and more of a down-dog. Another mistake is bouncing on your toes.
This exercise is suitable for beginners and can also be a good indoor cardio workout.
