IS ONE LEG BETTER THAN THE OTHER IN THE SADDLE?
You know the feeling: One leg lies beautifully against your horse’s side. The other?
Grips. Slides. Ignores you.
It is not your imagination, and it is probably not an issue with your horse. IT IS YOUR PELVIS.
When one side of the pelvis drops, you create a functional “shorter” leg. Your spine shifts off centre to keep your head balanced. Your seat bones load unevenly. One hip tightens. The other side overworks. And just like that—you have a good leg and a bad leg.
SO, WHAT IS THIS PATTERN COMPENSATING FOR?
Our bodies are made up of a series of joints, muscles and a nerve network. Efficient movement requires a sequence alternating between mobility and stability. Compensatory patterns happen when a joint lacks mobility and asks for a stable joint to move, resulting to instability in the saddle.
HIP JOINT: THE MAIN CULPRIT
A ball-socket joint, that is highly mobile, moving in multiple planes flexion, extension, adduction, abduction, internal, external rotation and circular. Stability provided by the deep socket, in which the head of your femur sits, and the surrounding ligaments and muscles.
Biomechanically speaking, the ability of the hip to move across multiple planes is closely coordinated with the pelvis and lumbar spine movement. If the hip joint lacks mobility it calls upon the pelvis and lumbar for help, increasing injury.
WHAT IS REQUIRED OF THE RIDER’S HIPS:
🦴—Shock absorption
🦴—The centre of control, requiring strength to keep the pelvis stable
🦴—Internal rotation to stabilise the legs—avoiding grippy knees
🦴—Adaptability between flexion and extension through all gaits—think squat for rising trot
🦴—To be open to provide a supple seat
WHY THE GLUTEUS MEDIUS IS YOUR SAVIOUR:
The Gluteus Medius plays an important role in creating a stable, supple and shocking absorbing seat. Often under-developed, the glute medius is your key pelvic stabilizer. This muscle:
🗝️ Prevents the pelvis from dropping
🗝️ Controls hip abduction
🗝️ Contributes to internal rotation
🗝️ Keeps your seat stable & shock-absorbing
When it is weak (or poorly coordinated), your pelvis tilts ➡️ When your pelvis tilts, your legs do not match ➡️ When your legs do not match ➡️ your horse feels it.
The Glute Medius is positioned on the outer surface of the pelvis, covered partly by the Gluteus Maximus and attaches to your femur (via your Greater Trochanter, which is attached to your femur).
Glute medius performs hip abduction (movement away from your midline) and internal rotation. Internal rotation becomes restricted when the back of your hip joint is weak, which involves your glute medius.
Many riders do not have enough internal rotation, with one hip being better than the other. This is the source of your compensation, restriction in your hip internal rotation leads to collapsing your waist ➡️ which is in turn makes your lumbar spine move sideways ➡️ the pelvis will drop off of one side of the saddle ➡️ adding more restriction in your hip and uneven seat bones.
MUSCLES WORK IN PAIRS
Muscles work in pairs: one muscle creates movement, while another counter-balances movement—creating stability, speed control, and prevents injury.
For the Glute Medius, it is our adductor muscles (inner thighs) at work. Your adductor (inner thigh) muscles together with glute medius stabilise the pelvis, control leg movement and balance hip abduction (away) and adduction (towards your midline).
Compensatory issues arise when your glute medius is weak, your adductors start doing the job of your glute medius becoming weak or tight, leading to poor hip alignment or injury.
PIRIFORMIS—PAIN IN THE BUTT
The Piriformis is a small muscle located deep in your glutes, extending from your Sacrum to your Femur. It stabilises the hip joint and aids in external rotation. When tight, it often creates sciatic-like pain in your butt.
This muscle in particular needs to be released most of all to help achieve internal rotation in the hip joint, thus creating that stability you need in the saddle.
HOW DO I FIX IT?
1. Release
2. Mobilise, and
3. Load
in that order, the afore mentioned muscles.
Glute exercises that are popular:
1. Squats
2. Lunges
3. Bridges
4. Deadlifts
1. The Gluteus Maximus, which extends the hip and externally rotates
2. Gluteus Medius, exercises that help your muscles abduct and internally rotate
If your hips do not rotate well in both directions on both sides, you cannot stabilise your pelvis in the saddle.
There is an important part many skip, which is to lengthen or elongate muscles. It is better to lengthen muscles BEFORE you strengthen them—this helps you develop body awareness before you load a muscle or joint.
If you strengthen on top of restriction, you reinforce the compensation. But let us not forget your weak/tight adductors.
The best way to lengthen your adductors is to roll them out with a foam roller or release and lengthen them over a physio ball.

FOR LENGTHENING THE PIRIFORMIS:
A release can be aided by rolling it over a spiky ball

WHY THIS MATTERS IN THE SADDLE
A pelvic drop can show up as:
🐴 A wiggle in rising trot
🐴 One canter lead better than the other
🐴 Resistance in lateral work
🐴 Lower Back, Hip or Knee pain
🐴 Increased pressure on one Seat Bone
SOUND FAMILIAR?
Modern life does not help—sitting, leg crossing, uneven posture. We take that imbalance from daily life straight into the saddle.
SO, WHAT CAN YOU DO?
✅ Check saddle fit—your pelvis needs support
✅ Improve body awareness (jaw tension and breath matter more than you think! Look up TMJ release exercises and neck stretches)
✅ Work on hip internal & external rotation
✅ Prioritise release and mobility BEFORE strengthening
✅ Use mirrors or video—what feels straight often is not
✅ Book yourself on a mechanical horse lesson with a rider biomechanics coach
Non-matching legs are rarely about bone length—they are usually due to lack of body awareness altering function of joints and associated muscles.
Balance the pelvis ➡️ restore rotation, and ➡️ reconnect mobility AND stability in the rider’s body! 🔄 💪
