About this exercise

A bodyweight core and cardio exercise performed with hands elevated on a step box, which reduces the angle of the movement compared to flat-floor mountain climbers. The incline position makes it more accessible while still effectively engaging the abs and hip flexors.

How to Perform

  • Place a step box on the floor and stand facing it
  • Place both hands shoulder-width apart on the top surface of the step box
  • Walk your feet back into a high-plank position, keeping your body in a straight line from head to heels
  • Brace your core and keep your hips level
  • Drive one knee toward your chest while keeping the other leg extended
  • Quickly switch legs, driving the opposite knee toward your chest
  • Continue alternating legs in a controlled, rhythmic manner for the desired duration
