Hi Robert – am glad to see you’re here!
Welcome mate, and, wishing you much success in your chosen fields of endeavour i.e. twinkling and honkin’.
Good tip i found on line is to purse your lips up and hold a pen horizontally before you go to bed at night.
Start slow maybe 20 secs and build it up to about three mins being to develop your sax embouchure.
All the best,
Mark
