Lie down on your back on the floor with your knees bent and arms by your sides.
Keep your lower back pressed into the floor.
Position the fingers of both hands at a 45 degrees angle just over your pelvis.
Take a deep breath in, allowing your rib cage to expand as much as you can.
As you exhale, tighten your belly muscles while drawing your belly button in towards your spine. You should feel the tension under your fingers as your rib cage lowers. Make sure not to arch your pelvis, shrug your shoulders, or hold your breath.
Hold the position for 10 seconds and then relax.
Aim for at least 5 repetitions daily.
If you find it difficult to "brace" your abs, try coughing during the exercise, which should easily create an abdominal brace.
