Hello-
Was wondering I am having a periformas condition in the right glute mild pain off and on and knowing the right glute complex is not as strong/balanced, how do I go about regaining a balance so the hams glutes
and back gain more posterior strength. I am 57 some stenosis in the back. I do yoga weighttrain,waterski,plyo's looking for some gains. thanks
