Hip Flexor Stretches If you’re like most people, you spend a large portion of your day sitting in a chair. The sedentary lifestyle can lead to very tight hip flexors. When I refer to the “hip flexors” there are actually a multitude of small muscles that I am referring to. One specifically is called the iliopsoas. The psoas muscle connects to the front of your hip but begins in your lower back. Thus having tight hip flexors can put a lot of strain on your low back. For those that have a hyper-lordotic curve in their lower back (sway back), stretching the hip flexors will give a nice relief and begin to rebalance the spine. These postures start out basic and get deeper and deeper. Feel free to take what you like and leave the rest.
