Hi everyone!
I have very poor mobility in my posterior chain. I can't even keep my back flat while sitting on the floor with the legs straight forward. I mostly feel it in my calves and behind my knee when I sit like this (although I know I am very tight in my hamstrings as well).
What do you think is the best way to increase this kind of mobility? Since I have not noticed much change with regular stretching.
Thanks and best regards
Anton
