Type of exercise
Begin in a pushup position on the ground with your hands placed firmly under your shoulders and your feet a few inches apart so you are in a straight line shoulder to hip to heel. Quickly drive one knee up towards your chest as though you were climbing a surface then rapidly switch legs. It is ok to start slow and build speed over time!
The Mountain Climber is an excellent way to train both core strength and metabolic conditioning depending on how it is incorporated in a program.
