Lunge her until she is dropping her head or at least blowing in both directions, and when riding do lots of transition work, stretching, serpentines, something to keep her thinking and hopefully that will get her to relax. For hot horses I find you really want a good warm up routine before you start working. Good luck, I hope you find some of this useful!
If she is a hot horse then lunging her could potentially rev her up even more
Don’t lunge her but if you do lightly and trot her for a while and keep working her down
You can try lunging her everyday for a week or two before actually riding her
There’s this horse that I’m supposed to start training. She’s been out of work for the past 6 months due to being lame and she’s now allowed to be worked again. She was already quite hot before so no doubt she’ll be worse after not being ridden for some time. I’ve been told to lunge her before I ride which I will do but any other tips?
