Would you like to shorten your hip flexors?
Would you like to cause burning back pain?
Would you like to create a posterior herniated disc?
Or maybe even pull your rib cage closer to your pelvis so you can look like a cave man?
Well then do I have a solution for you!! You can have all this and more in ONLY 3 minutes!! All you have to do is what the pros in the NBA do!! Boy those Phoenix Sun Trainers are some smart fellas ;)
Seriously though, watch when he stands up. He has shortened his hip flexors so much that he can not even stand up straight!! FOLKS, DO NOT DO THIS!!
