Learning to engage your core while moving your upper body and NOT moving your hips is essential to a powerful and balanced swing. This is a great exercise after any lower back issues. It is challenging and can be made even more so with the use of a weighted ball.
Sit on a medicine ball. Slowly, arms across your chest, raise each leg and twist with arms across your chest. Do this exercise slowly and to both sides. Switch legs. Do each direction 5 times. Add a weighted ball to increase the difficulty.
