Hi Sunny. From within the app search workout for the keywords 'back pain'    about a half dozen workouts with that in the name pop up near the top of the list. Good luck!

Dear back is most sensitive part of body so done exsersize in proper manner.....

Hey wazzup
My personal recommendation is u must have
-chin ups (proper slow form)
-lat pull downs (slightly arched back)

I hear you. Took me a couple months to figure all of it out! Anyway, welcome to the community!
