This exercise helps to build strength in your glutes and lower back, helping to support the SI joint. To perform this exercise, lie on your back with your knees bent and the arms against the body and palms against the floor. Squeeze the buttocks and raise the hips off the ground to bring the torso into a straight diagonal line. Hold this position for 5 seconds then slowly lower yourself back to the ground. Repeat 8-10 times.
