If you spend a lot of your working day seated at a desk, there's a good chance that you already have, or one day will have, some lower back pain. Standing up and walking around every now and then can help, but if we're too busy or focused on a job, we might not be able to do this. The good news is, there's a very easy exercise you can do to help with lower back pain — and you don't have to stand up to do it! The exercise is called "seated salsa" — because just like in the salsa dance, your hips roll forward and back when you do it. This is how you do it: Sit up straight and make sure your feet are touching the floor, with both knees pointing straight in front of you. Without moving your shoulders, push your right knee forward and pull your left knee back, then push your left knee forward and pull your right knee back. Keep doing this for one minute. According to the BBC, a recent study in the UK found that one minute of seated salsa every 30 minutes can help ease pain by relaxing the muscles in the lower back. Seated salsa could also be useful for older people who can't stand up so easily, or for people getting over health problems who can't move around very much. So why not try a little seated salsa — and keep your lower back pain-free!
