What is your understanding of join up?
Is it something you rely on and can't do without or is it something you see no use for at all or do you find it an occasional thing to fall back on
Would you use it in what many call a predator/prey sense where the horse is run around to the point where it either feels exhausted and gives up because its defeated or because its bored and wants to 'play a different game'?
Do you see it as a form of liberty work - alongside lunging/longeing where the horse is working in a disciplined situation obedient to voice commands or body language?
Should your body language be quiet and understandable to the horse or should it be aggressive and intimidating. Do you know the difference?
These are two very opposite thoughts on the use of round penning (as I see)
The first is using it as a means to exhaust a horse that's afraid of being sacked out with a rope. The person mentions running it around approx 100 times. The horse then accepts to rope because 'it was made harder to not accept
Is this horse a willing partner now or is it a begrudging surrender?
There is a lot in between
NOTE - This is not about the 'trainers' here or if you like or dislike them so please don't get into that.
Thoughts please not arguments
