My father has suffered from a bad back for most of his life. He’s thrown it out a quite few times, but it isn’t really damaged.
I had the same thing when I was younger before I started yoga, but I don’t think I can start him on my routine because his back muscles are weak and any dramatic activity causes him some pain. He also fears throwing it out, so he’s worried about the type of exercise.
Could you suggest a safe exercise/exercises that would stretch/strengthen his back?
