Hi I’m in my early fifties and wanted s bit of advice from regular yogis please. Recently started yoga again after 25 year gap (!) as I’m starting to seize up. I have really achy joints and thought it’s now ‘use it or lose it’. I am really not supple and can’t even do beginner poses comfortably. I know it takes time to regain flexibility but have I left it too late? Any thoughts? Thanks.
