I see it all the time: people with the kind of lower back pain that leads them to believe they should avoid exercise and stay in bed. What these people don't know is that nothing could be further from the truth - the best way to heal is to get moving!
So often, workouts that stress the lower body (particularly the glutes and hamstrings) will lead to tightness and DOMS (delayed onset muscle soreness) in the following days. When those muscles tense up, they pull on the lower back, causing that unmistakable pain.
I have had so many clients tell me that their workouts hurt their back, even though I was there to ensure that their form was perfect and that there was no unnecessary stress on their back. What they didn't realize is that the muscles they worked, especially in exercises like deadlifts, glute bridges, squats and explosive plyo jumps, were simply tight, causing pull on their lower back. By stretching those muscles, the pain was alleviated!
Sometimes, however, stretching isn't enough. In those cases, it's important to walk around and get the muscles moving and the blood flowing. Staying seated and favoring the muscles will only ensure that the discomfort lasts.
The next time you have tight, achy muscles or annoying lower back pain, stretch out the muscles of your lower body and go for a nice walk! You'll feel better in no time!
