You are correct, holding with the core, except to me that translates to putting weight in my stirrups too. The sitting heavier and holding my core is what seems to work for now. I was a hunter/jumper in my early 20’s and now doing dressage for a few years in my late 30’s. Changing muscle memory is harder than learning a new language LOL! I’m lucky to have a very sensitive horse who needs to be ridden and asked just right - it makes you learn faster : ) The other challenge now is learning half pass when all I’ve done is leg yield for years! Anyone care to describe that? My horse will do it simply with a shift of weight for my trainer, but I can’t figure it out!![/QUOTE]
But be careful that putting more weight into your stirrups does not lead to “standing” in the stirrups. I don’t mean literal standing but the effect of locking the hips and not sitting deep and with the motion. I have a habit of doing this when horsey takes over in the canter and while I think I’m sitting into it more, my heavier weight in the stirrup is detrimental as I start to lock my hips slightly.
What I need to be doing is following the motion but adding more lower leg aid to rock him back on his haunches. It is super duper tempting to stop with the hand and take the leg off in horse the braces or take over when we need to do the exact opposite, use less hand and more seat leg aids to sit them down and then they can lighten and bend correctly.
Use small circles to your advantage, if you feel him braced or taking over use a 10m circle to bring him back, bend and rebalance him. You might need a circle every ten 10-15m until he has the strength to hold himself soft and balanced. Also 10m circles help prevent “pulling” and encourage you to ride it.
As for half pass you need to master shoulder in and haunches in first. Half pass comes from being able to ride the horse forward with bend diagonally. Some describe it as haunches in on a diagonal line, but I think of it more as the bend felt on a circle forward and over with shoulders leading (driving forward inside leg and respecting the outside leg to go over). When you think of the bend of a circle then you tend to weigh your seat bones better. Too many people incorrectly have their weight on the outside seatbone thinking unwisely that they are moving the horse over or they collapse in their hips from trying too hard. Also you must give enough on the outside rein to allow the bend and not kill the hind with false neck bend, you can’t pull the horse into bend (another common fault) which is why mastering SI and HP first is important. I prefer to ride shoulder in then go into half pass but you will find people have many different preferences.
