Find a bosu and place it in front of you. Stand up straight with your feet at shoulder width apart and your hands raised in front of you. Contract your pelvic floor and core while keeping your chest up.
Step forward in the bosu with your right leg making a 90º degree angle between your legs and bending your knees, slowly lower your body down until your right knee almost touches the floor while you inhale. Make sure to keep your right shin perpendicular to the floor avoiding the rise of the heel. Pushing mainly from the heel, return to the starting position while you exhale. Make sure you don't move your torso backwards while you perform the exercise. Repeat the movement for the specified amount of repetitions and then repeat with the other leg. While your are doing the exercise, move only the legs, make sure you don't move any other part of your body.TIPS: To maintain the balance, try to move the feet always in the same line without crossing them.
