You have to have a good inner thigh to be able to post without stirrups. I can because I have worked really hard at it. You can practice without stirrups on a bouncy horse (SAFELY!) sitting, a slow trot/jog. then get back on your horse (which i assume is not particulary bouncy) and posting should be easier. remember not to accidentally kick your horse while trying to do so!
Posting trot.

No, posting or rising trot is a way to ride the trot and you can post any type of trot. Extended trot is where the horse lengthens it's trot stride to cover more ground. Typically this causes the trot to smooth out a bit making it easier to sit the trot.
A sitting trot in English riding or hunt seat is simply a slower trot in which the rider does not post. The rider takes a deep seat and absorbs the horses movement without posting in the saddle.
Another name for the rising trot is the posting trot. This term is commonly used to describe the motion of rising and sitting in rhythm with the horse's trot, helping both rider and horse maintain a balanced and comfortable gait.
sit deep in the saddle and keep your heels down
The posting trot
"you can walk trot and without stirrups canter" This would make you an experienced rider... "you have been out on one half hour hack with about 6 other riders in a small country lane" This would place you as an experienced novice...

Well I would say novice, simply due to the fact you didn't mention canter work.
The trot, whether it be extended, sitting, or posting is still a 2-beat gate.
doing rising trot without stirrups improves your balance and seat. 1. Don't rely on your horse rise and drop down gently but quickly never let the horse choose what you do. 2. Keep a straight back and reinstry not to drop side to side.
