Riders tend to think that the stiff side is the bad side because it feels harder for them to bend their horses when that side is on the inside. But you need to think outside the box.
The stiff side is not the problem. Your horse feels stiff on one side because the muscles on the other side of his body are shortened and contracted. Those shortened muscles limit how much he can stretch and bend around your other leg.

So, let’s say your horse is stiff (hard, strong) to the right. The benign antagonism solution to this problem is to stretch the shortened muscles on the left side by riding your horse with too much bend when you track to the right.
In schooling, you’ll live in “right bend” until you feel the muscles on his left side elongate. (You’ll know those muscles are stretching because it’ll feel easier to bend your horse to the right.)
BENIGN ANTAGONISM – GETTING YOUR HORSE TO BEND

Put simply Benign Antagonism means that you kindly and quietly do the opposite of whatever your horse chooses to do on his own.
For example, if your horse likes to carry his head too high, then you ride him deep. If he likes to put his head on the ground, then you ride him up. If your horse likes to go too fast, then you work him in a slow tempo.
How To Soften Your Horses Stiff Side
Here’s an exercise to gently stretch and elongate the muscles on the left side (the hollow side) of your horse’s body. Track to the right for this exercise.
NOTE : If your horse is really stiff, do the exercise at walk …
- Move on a large circle to the right.
- Pick a point somewhere along the arc of the circle, and turn onto a 6-meter circle.
- While on the small circle, think about your bending aids.
- Put your weight on your right seat bone, keep your right leg on girth,
- Place your left leg behind the girth
- Flex your horse to the right by turning the key in the lock with your right wrist, and support with your left hand.)
Ride the 6-meter circle a couple of times until your horse’s body conforms to its arc.
Once you’ve got your horse to bend, keep applying the 6-meter bending aids, but blend back onto the 20-meter circle.
If it gets difficult for your horse to stay bent this much to the right, blend back onto a 6-meter circle. The idea is to ride the 20-meter circle with a 6-meter bend.
Once you can do this on a circle, try riding straight down the long side with your horse bent as if he’s on the arc of a 6-meter circle.
(The feeling is a bit like doing shoulder-in in front and haunches-in behind at the same time.)
How Do I Make the Hollow Side Stiffer.
The flip side of this stiff to the right issue is that your horse will be hollow or soft to the left. You might think his soft side is his good side because he feels easier to bend, but the hollow side of your horse needs help as well.On the hollow side, your horse usually doesn’t have true bend-equal from poll to tail. He usually overbends his neck to the inside and places his inside hind leg to the inside of his line of travel. By doing so, he can avoid bending the joints of his inside hind (engagement). He doesn’t carry as much weight on that hind leg. As a result, that leg gets weaker, and he develops unevenly.
My benign antagonism solution for this problem is to ride without any bend at all when the hollow side is on the inside. Keep your horse as straight as he is on the long side even when you go through corners and circles. Think that his body is like a bus that can’t bend on turns.
So, let’s say your horse’s hollow (soft, weak) side is his left side. When circling to the left, ride without any bend at all. Keep his body as straight as a bus.
To get a perception of straightness, halt somewhere on the long side. Make your horse’s body parallel to the long side all the way from poll to tail.
Also, ride him either with no flexion (His chin is lined up with center of his chest.) or in counter-flexion. In counter-flexion, his face will be 1 inch to the right.
Ride through corners and circles with no bend through his body and in counter-flexion at his poll. If you ride in this position, your horse’s left hind leg will step underneath his body.
This will make that leg stronger over time.
