You should find a box at the height of your thighs and place it in front of you. Stand straight with the box at your right side and spread your feet at shoulder width apart. Contract your pelvic floor and core while keeping your chest up.
Place the entire sole of your right foot on the box. Pressing mainly from your right heel, step up on the box in a fast movement. Step down with a smooth movement and repeat the exercise with the other leg.TIPS: Make sure your knees are always pointing towards the toes. Focus on always having your weight on the entire soles of your feet. Your head and chest should always look forward.
