How to perform mountain climber exercise properly:

  • Assume a press up position so your hands are directly under your chest at shoulder width apart with straight arms.
  • Your body should form a straight line from your shoulders to your ankles.
  • Lift your right foot off the floor and slowly raise your knee as close to your chest as you can.
  • Return to the starting position and repeat with your left leg.
  • Continue alternating for the desired number of reps or time.
