1. Lie flat with your knees bent.
2. Put your right hand on your stomach (or your left hand if you are left-handed), palm down, fingers pointing to the pubic bone, and hands on your navel.
3. Inhale, then exhale, and gently lift your head and shoulders off the ground, just like doing sit-ups. It doesn't matter if your head and shoulders can't leave the ground. Just try this action to make your abdominal muscles start to contract.
When you try to sit up, you should feel your abdominal muscles contracting. If you have rectus abdominis separation, you should be able to feel it. You may have to do it a few more times to feel it. If you try three times in a row and feel nothing, don't do it again.
5. It is normal that your abdominal muscle gap is less than 2 fingers wide after delivery. If your gap is more than 3 fingers wide, you need to start doing some pelvic floor muscle exercises and lower abdominal muscle exercises to avoid doing sit-ups. If your abdominal muscle space is still more than 3 fingers wide after a few weeks, you must go to the hospital to consult a doctor.
