Hi,
My shoulder/thoracic flexibility is awful but very slowly improving through the use of the stretch series however I get frustrated because I cannot do some of the later exercises in the series at all. The main example is the elevated bridge, as soon as I raise my feet even a little I cannot push off the floor at all, I am not sure if this is a thoracic flexibility issue or a weakness in the arms, any tips on intermediate exercises/stretches would be great, thanks.
Chris
