If you do this exercise correctly, you will strengthen the entire central part of the body and strengthen the lower back, which will improve your posture. Such a deep breathing technique is part of Pilates and yoga, but you can work it out separately from these types of exercises.
- As soon as you wake up (ideally on your empty stomach while still in bed) lie on your back with your bent knees, and your feet resting on the bed. Take a deep breath and pull the stomach as hard as you want to stick your navel with your spine. The more you extinguish it will be the stronger contraction and effectiveness of this movement.
