About the last 10 years my sports injuries and just getting older in general have created a lot of back pain, especially when I sit on stand for a long time. It just takes away the fun of being in the woods. Here are three stretches to help you out. The first one has given me a great bit of relief. I do it before work and after every workout. My left hip has been horrible for years and it has started effecting my left knee. Within about 2 weeks of using this stretch Ive noticed my back pain while seated in my car at work has really improved. The second stretch has helped my hips out and I do it twice a day for 30 seconds. The final one stretches the upper hamstring. Consistently do these three stretches and you will notice a big difference in that lingering back pain. Should make your hunts more enjoyable.
