After a few hours of sitting at your desk or driving home from work, you may start to notice yourself slouching in your seat. Maybe you need to pick up something off the floor and your initial reaction will be to bend down at your waist thinking it is no big deal. Then you are standing in line at the grocery store with the shopping basket dropping your arm down after you picked up more supplies than you had originally anticipated. Do any of these scenarios sound familiar? All of these everyday scenarios have a negative impact on your muscles and joints. After a while, you may start to feel soreness in your lower back. If you find you can relate, it is likely that you have bad posture.
