To do this stretch we are going to use any upright post. Here Dion is using the doorway.
There is a natural curve in your lower back and we are going to remove this by placing your backside, upper back and head on the post and then gently draw in your belly button and contract the rear leg, to decrease the arch in your lower back. This tecahes you to activate the tummy, backside AND stretch tight hip flexors.
NOTE: A good test to see if you have tight hip flexors is lay on your back on the edge of your bed and hug your knee to chest. If the relaxed leg feel’s tight in the front of hip (hip flexor) and the knee is slightly lifting, so that you are not straight (therefore knee rises to a positive degree) it would seem you have tight hip flexors. Or work with your PUSH_ Trainer in a thomas test or sprinters stretch test!
