Try this ab exercise for low back pain if you experience a lot of pain after sitting for long periods of time. It’s different from a traditional situp, and very effective for strengthening abdominal muscles.
Start by sitting on the ground. Bend your knees slightly so your feet are resting on the ground but your legs are out long. Your knees should have about a 60 degree bend.
Place your hands behind your neck. Keeping your core muscles engaged, breathe out and lift your right leg, bending your knee and bringing it back toward your body as you twist and lean forward until you touch your left elbow to your right knee. Breathe in as you release your leg back to the ground and lean back again, coming to a central neutral spine. Repeat on the other side, bringing your leg up to meet your right elbow.
Repeat this ab exercise for low back pain 15 times on each side.
