How do I keep heels down and what can I do to improve my sitting trot?
To improve your sitting trot is my best advice to ride bareback. I have ridden bare back so much in my days and it has really helped me a lot to improve my position. Especially in the trot.
Do you havne any tips to get a horse up to canter without trotting faster and loosing control ?
You can't rush into a canter. You have to pull her back make her trot slower and then make It very clear for her that you want her to canter as you give her the canter signal you also pull her back a bit so she can't rush into canter. I don't like the idea to use whips or Spurs because if you can't get your horse to canter without these stuff then we have something to work with.
