The leg raise is the perfect exercise for the somewhat neglected lower abdominals and hip flexors. Regular performance of leg raises can help to strengthen the lower back and therefore reduce the risk of injuries. You will need a mat to lie on for this exercise and some people who experience lower back pain may want to pop a towel under their lower back area.
