2. Hip Flexors Stretch
Tight hip flexors are a common culprit in low back disorders, hip pain, and knee pain. Sitting all day encourages the muscles to shorten, which is why maintaining flexibility and getting up out of sitting position frequently is important. To stretch the hip flexors, start by standing in front of your chair, facing away from it. Place one foot on the back of the chair and bend the knee of the supporting leg to allow you to sink into the stretch.
You can intensify or modify the stretch by squeezing the glutes on the stretched side. Another way to modify the stretch is to add the same arm as the side that is stretched; reach over your head and bending slightly towards your opposite hip. Follow this stretch by simply squeezing the glutes while standing and it will further encourage the hip flexors to relax.
