something tells me that you are not nearly disciplined enough to begin focusing your Chi, grasshopper. Why don't you move to China where masters can teach you about focusing your Chi. Then you will be able to chop down big mountain with foot.

focus on the stretch of your legs and the stride. the bigger you stride, the more effortless it is to go faster.

you cant use chi for make higher or run faster before you can control your chi. After you can control chi, you can make spectakuler movement.
Chi can control with breath and mind control training

Beautiful are the "feet" of those who preach PEACE.
Peace is 'higher' than division and not peace 'on high'.
Peace is 'above' law vs law and law vs grace divisions.

Eg: Pauline Epistle Format (frm the top dwn approach)
Head: Greeting of Grace & Peace to U frm God & Son
Body: a discussion of law vs grace in allegoric forms
Feet: The GRACE of our Lord JC with you all. Amen.

Note: the last Amen goes to the feet, to the conclusion,
when considering what's frm God and frm Jesus Christ.
Beautiful are the "feet" that do the grace run unto peace,
is as if an end "run" along "with patience" in Hebrews 12.
So patience isn't walking, but "run"-ing the human "race".

So, may your grace us feet do the end "run": Heb 12,
by dropping the weight(law) that so easily besets, to
pick up the pace of the race, run along with patience,
hastening to day of God, not day of the LORD: 2Pet3,
for the day of the LORD is darkness, not light: Amos 5,
and making it to the end, alive unto God, is "grace" only:
The GRACE of our Lord Jesus Christ with you all. Amen.

So yes, Jump higher, Run faster, Do the end "run",
with grace us merciful feet, unto peace for you & all,
you and all the kingdom of God located "within you":

Grace –> Mercy –> Peace to you all from God & Son.

Don't worry about chi. Worry about training.

Yes! Jump on every ride.
Something better to do with her and you. Blindfold your horse, with something like a t-shirt or cloth. lead your horse over cross rails laid out over a spread of at least 20 ft. and lead her over and over across them, talk to her and let her know that shes fine.
When she has full trust with you, then you can move on.
Get on her while shes blind folded. Meaning, she has to have complete trust to know that you won't ram her into something like a fence. As you continue these exercises (BOTH) daily or every time you ride both of you will have a closer relationship and will trust each other to the fullest extent.
And depending on high you won't to jump her is how much advice i can give. =) I would say keep doing those exercises and jump over small fences to still gain trust, then go higher and higher each time.
Another really effective thing to do is put your horse on a lunge and put out some small jumps, like one or two. Jump her over those while warming up before a ride or something…..Good luck and best wishes with your horse!! =-) –Equine Experts

Yeah, you should really.

But to get started with the jumps, you should putt small branches on the ground. Tear off all of the other branches, leaving only one. Don't use a pine branch, one that is rotting, or even one with spikes. If you can't find some branches, go to a lumber store and buy square wood pieces, that are long.Basicly, rectangles. Get her to cross them. DO NOT USE PLASTIC PIPES. If she would step on the plastic pipes, they would break and she would would hear the noises and all this and that, you'd probably hit something, and she could run away, and a big mean bear could get her. (( No pun intended at the start.))

A good idea for her to relax once in a while is if you have any veternarians around with horse pools and underwater treadmills. This really relaxes their leg and helps them get used to the water too.

If your horse isn't afraid of water, have her jump over some small puddles. Jump in them before, but make sure somebody is with you. Puddles can be sinkholes and you could die. Or live in mud for the rest of your life.
