What's happening
One side feels heavier than the other is showing a load and movement organisation issue, not a willpower issue. Your body is switching into a compensation strategy under movement. That is why the same pattern keeps returning when demand rises.
Why it happens
- Load transfer is inconsistent under movement.
- One part of the body is holding to create control.
- Pelvis and trunk are managing movement late instead of organising early.
- The current strategy works briefly, then breaks under more demand.
- Compensation pattern keeps repeating around 'one side feels heavier than the other'.
The Exercise
Peanut Ball Pelvic Organisation Session
- Equipment: Water-filled peanut ball under both seat bones.
- Set-up: central body organisation before adding demand.
- Set-up: neutral pelvis, legs under body, soft joints.
- Progression: start in lower movement, then increase demand gradually.
- Progression: remove support when organisation can be maintained.
- Key focus points: Let pelvis carry movement. No holding through thigh or trunk.
- Key focus points: no pushing down or bracing to create false stability.
- Key coaching cues: If you have to hold it, it's not organised.
- Key coaching cues: Allow movement, don't manage it.
- Key coaching cues: Let movement happen, don't manage it.
What this changes
- Pelvis: held response -> more adaptive response.
- Load pathway: disrupted -> more continuous transfer.
- Compensation pattern: dominant -> reduced.
- Aids: reactive support -> clearer function.
- Problem expression ('one side feels heavier than the other'): less frequent and less intense.
What the rider should feel
- Less need to hold for control.
- More even left-right awareness under movement.
- Legs and trunk feel available instead of braced.
- Changes in movement feel less disruptive.
- Organisation feels repeatable, not forced.
Transfer check
After removing the support:
- Does 'one side feels heavier than the other' reduce when movement increases?
- Can you keep organisation without gripping or bracing?
- Do aids stay clearer under pressure?
- Can you maintain change across transitions or directional changes?
- If not: return to the exercise.
Progressions
- Add rein organisation challenges.
- Add transition tasks with less reset time.
- Add no-stirrups blocks where appropriate.
- Add poles or dynamic position work once stable.
- Add layered tasks only if compensation does not return.
