I run a Putting Group on the CoachNow app that anyone of any level can subscribe to.  This is the perfect way to practice from anywhere in the world in your own time using the info and experience I have collected in over a decade of putting coaching.
There are various channels on what I like to see in a putting grip, putting setup, putting stroke.  There are channels dedicated to green reading, the mental game, and many drills you can use to help you putt better!  There’s also advice on HOW to practice effectively, something not many golfers are aware of.
Whilst my putting group is mainly based around my specialism of putting, there are some full swing and short game videos in there you can use to help your general game.
