activity ideas??

This is my first time posting on here so if its weird bear with me. I have been riding an arab mix for 4 years and he has become the perfect horse. He has transformed from an unpredictable dangerous ride to a willing and brave. I also take lessons on other horses and ride at a few barns but keep coming back to my baby.

Anyway now to the problem. He responds really well to challenges and new activities but it is winter and my facilities are VERY limited(a field that is often too wet to ride, a round pen, long stretch of dirt road, and trails). He is behaving well and I am out of ideas to keep him entertained. Without new challenges, he gets restless and either his spookiness comes back or he turns into a zombie.
For the natural horseman people, he is a Left brained extrovert.

He has an old injury and cannot jump anymore, I am working toward high level dressage. He can pilaf, canter pirouette, leg yield at canter and trot...(not perfectly but well for my skill level)

My main focus right now is improving our flying lead changes but I can only work on this for about 10 minutes at a time before he gets either bored or frustrated.

I need activity ideas, training ideas, new things to teach or my favorite ride will lose his mind again.

I got all the ideas I needed and more from these books, so I'd suggest reading them :) -

For groundwork google horse agility. All kinds of great ideas there. Some can be done under saddle as well.

You could try some liberty or tackless work in the round pen? On the dirt trail, set a mini dressage test for yourself. Half pass to this tree, change leg at next bush, work on transitions or even just have a good gallop
If you do Parelli, make an obstacle course for yourself using the 7 games - or even a ridden one!

If your horse really enjoys learning new things, maybe you could teach him a few tricks! My ex racer is also an LBE & he loves performing There are loads of trick training websites with some really good information :)

thanks guys, very helpful with the links and everything, ill have to chack everything out... and I finish every ride with a good gallop :)

What is pilaf?

I am curious as to how he can perform a canter pirouette, a movement requiring an immense degree of strength and balance, but is not established in the very basic movement of leg yield?

High level dressage horses have a lot of stress placed on their bodies and need to be very much sound of mind and limb. A horse that is unsound to jump, is going to be unsound for high level dressage.

He has the leg yield, has had it for years. He is very sound but the shock of the impact landing after a jump is the problem. Long term stress is different and I have clearing from a vet for all that I do.

I meant passage, my mistake and we are still working on developing all the muscles for this.

Did you mean piaffe? Trotting 'on the spot'? I'd be curious to see some video of this... as its takes years upon years of gymnastic, balance and careful education of a dressage horse to develop the strength and balance to perform this movement. Same goes for passage, it is an extraordinarily strenuous movement for a horse to perform, piaffe can be 'faked' as a party trick, passage not so much. Considering these are two movements which often prevent a horse from getting to the top levels of the sport... I'm quite impressed that you can do them on your horse.
