Mountain Climbers is a popular bodyweight exercise that targets multiple muscle groups, including the core, arms, and legs. It involves starting in a plank position and then quickly bringing one knee towards the chest, alternating legs in a running motion. This exercise not only builds strength but also improves cardiovascular fitness. Mountain climbers can be performed anywhere, making them a convenient option for workouts. They can be modified for different fitness levels by adjusting the speed or intensity. Incorporating mountain climbers into a routine can enhance agility and endurance, contributing to overall physical fitness.
