I'm having trouble with my back. Can you recommend any stretches that can help?

1.  Start by standing up straight, then bend your knees and place the palms of your hands on the floor in front of you.
2.  Keeping your back straight, slowly walk your feet towards your body until you feel a gentle stretch in your lower back.
3.  Hold this position for 30 seconds, then release and repeat two more times.
4.  You can also try yoga poses such as downward facing dog or child's pose to target specific areas of your back.
