I'm a 1 year in, 34 year old rider (returning to the sport after 20 years). I started leasing about 2 months ago and ride 3 times a week.
Lately I've been practicing my sit trot so much, I'm actually almost more comfortable sitting the trot than posting. This sounds crazy to me, but it's true. :)
When I sit, I feel I can get my weight down into my stirrups and feel I'm more consistent down there. When I post, I clearly use something down there to drive myself up as posting w/o stirrups is quite a challenge. I often find this is when I feel inconsistent from the knee down. Maybe more weight when I stand / less when I sit?
I practice stirrup-less a lot too and want to start practicing posting w/o stirrups.
My question is.. when you post w/o stirrups clearly you do not use stirrups and so you rely more on the bounce and your leg muscles to post.
Is this more proper? Aka would it be good to for me to practice stirrup-less posting and when when back in the stirrups try and make it feel the same? It would be a deep seat for a post i'm sure!
Feel free to correct any wrong assumptions I might have :)
