The cross-body mountain climber is a popular bodyweight exercise targeting the muscles of the core, as well as the shoulders, hips, and cardiovascular system. It is different from a traditional mountain climber because you bring the knee to the opposite side of the body rather than simply to the chest. It can be performed for time or reps as part of a dynamic warm-up, for bodyweight cardio or conditioning, or as no-equipment dynamic core training.
Greater oblique emphasis than traditional mountain climbers
Serious cardiovascular challenge and calorie burn
Teaches core to brace while lower body moves
Great movement for high-intensity interval training (HIIT)
