This is a great strengthening exercise that keeps your core muscles nice and strong as well as helping to reduce lower back pain!
Start by kneeling on all fours, your hands should be beneath your shoulders and your knees directly below your hips. Engage your core muscles and slowly lift your right arm extending it out in front of you keeping your arm straight then slowly lift your left leg extending it back, keeping it straight and pointing your toes down.
Hold for 10-30 seconds before slowly lowering back to your starting position. Repeat three times on each side. Remember to keep your core engaged the whole time!!
