I’ve been enjoying this website by a pair of British trainers who seem to do only Positive Training. I do alot of clicker training for ground work with my mustang convert but conventional training for under saddle. It seems fine to combine to two methods. I found it an interesting insight into that way of working with horses though.

Also you could check out Warwick Schiller - he has lots of doable training videos. I have really benefitted from his way of going slower when the horse says no. Has made me a more thoughtful trainer!
I also like Jonathan Field who does amazing liberty work. He has a complete series you can by but also lots online.
and for fun inspiration - Sam van Fleet who competes in mustang makeovers. I like her earlier liberty training videos (made when she was a teenager!), more than the actual prepping for competition in mustang makeover events.

Mustang Maddy was very fun for awhile, but she doesn’t seem to be posting new material.
Have fun!
