Core stability exercises that can help strengthen the necessary muscles of your core and may help reduce the risk of lower lower back pain.

In the above video, Kenny from Physio K runs you through a program of 4 simple exercises.

1. Glutes bridge with leg extension

Laying on your back on a mat, try to lift your bum off the floor and make a straight line between your knees and your shoulders. Then extend one knee and hold for 3 seconds and alternate between your left leg and your right leg. Try to do 10 repetitions each leg and do 3 sets.

2. Bird dog

In all fours position, with your hips above your knees and your shoulders above your hands. Try to extend 1 leg and the opposite arm. Hold for 3 seconds and then switch sides. Do 10 repetitions and 3 sets.

3. Plank with alternating leg lifts

Come in a plank position, make sure there is a straight line between your shoulders and your feet. From that position, lift or extend 1 leg and hold for 3 seconds and then alternate to the other leg.

4. Windshield wipers

Laying on your back on a mat on the floor, having your hips and knees bent in a 90 degree angle. From there, go to 1 side, hold for 2 seconds and then switch to the other side. Your shoulder blades should touch the floor at all times.

These are effective, well-tolerated exercises to help strengthen your core muscles. They may help reduce the risk of lower back pain and build a buffer to help you stay strong.
