hey guys,
just looking for a little guidance regarding which route i should be taking my GB training as a long distance runner. to be more specific, i just finished Fundamentals and now i'm wondering if it would be more beneficial for me to go with the Foundation Series, or something more along the lines of the Stretch Series/Popular Package. i have no intention of beefing up my upper body, rather my focus is on strengthening my core and all the connective tissues/joints in my legs, so i'm a bit lost about which would be more beneficial.
any advice would be greatly appreciated..
thanks!
