Hi - I have become interested in the program initially because all my life I have been stiffer than a board and it now as I getting older (currently 39) I have started noticing the negative impact of my inflexibility.
Especially when it comes to my lower back.
Will this program (if so which one in specific) help me become more flexible and more importantly which one of the programs would be most recommended in improving the condition of my back?
Thank you
Peter
