Modified Plank

Place yourself in a push-up position, with your legs extended behind you, hands placed on either side of your head. Next, place your forearms on the ground, palms facing down, shoulder-width apart. Holding this position, raise your right leg up by a few centimetres and lower it again, repeating the movement 10 times. Do the same with your left leg. Throughout the exercise, contract your abdominal muscles and don’t release, making sure your body forms a parallel line with the ground. Do two sets (of 10 repetitions with each leg).
