Q: My horse is always more resistant on one rein. Is this normal, or is something wrong?

A: Most horses are naturally one-sided, meaning they’re more supple or ‘willing’ on one rein than the other. This asymmetry can be due to conformation, habitual patterns, or even the rider’s own crookedness. While a degree of ‘sidedness’ is normal, significant resistance may indicate muscular imbalance, dental issues, poor saddle fit, or undiagnosed lameness so it’s worth ruling out pain first. From there, consistent work on symmetry—such as lateral movements, stretching exercises, and polework—can improve balance and suppleness. It is also advisable to work with an experienced trainer to assess both you and your horse, and to employ the services of a physio if possible. In the long term, creating symmetry will not only improve performance but also reduce the risk of injury from compensatory movements.
