That's what I was going to add in my first reply.
Be sure any PT you go to is very advanced and an expert at what they do -and for sure NOT a rookie!

Overall posture comes into play
proper and gentle stretching
if there is pain, spasms or triggerpoints those need to be resolved & released first before any kind of strengthening is even attempted.

This all depends on where your pain levels are on avg too.
Do you get delayed pain? hours or a day after certain activities?
