Hi,
I've been training Foundation One for over a year now and I've discovered that I have extremely tight hamstrings making it very difficult for me to do some of the exercises (swivel hips for instance which I've been stuck on for over a year). Prior to GST, I was doing basic barbell training (squat, deadlift etc) which I assume is why my hamstrings are so tight. I've only got time to commit to one stretch series, which one would be the most beneficial to address my deficiencies?
Thanks for your help!
