Stretch Reflex : Resistance

Working with Resistance?

Lasting change comes from reducing the need for protection, not forcing the body past it.

When movement is gradual and well-supported, the stretch reflex becomes less reactive. Breathing, pacing, and position all play a role in signalling that the body is safe to release.

This is why, in practice, a slower and more controlled approach often leads to greater range than pushing further into discomfort.

This becomes clear in simple positions such as forward folds, where pushing deeper often increases tension, while slowing down allows the body to release.

Trust the Process

Many people assume they are simply “not flexible.” In reality, flexibility develops as the body learns that movement is safe.

With consistent practice, resistance becomes easier to work with, and range of motion improves without force. What changes is not just the muscle, but the way the body responds to movement.

Muscles don’t resist stretching by accident. That resistance is often the stretch reflex - a protective response designed to prevent overstretching. Improving flexibility depends less on pushing further, and more on understanding how to work with this response.

What is the Stretch Reflex?

The stretch reflex is a built-in protective mechanism. When a muscle is stretched quickly or beyond what feels safe, sensory receptors detect the change and trigger a reflexive contraction.

This is why pushing deeper into a stretch can sometimes create more tension rather than less.

Why It Happens

The body is organised around efficiency and protection.

Muscles adapt to habitual positions - prolonged sitting, for example - and over time the nervous system becomes accustomed to a limited range. When you try to move beyond that, the stretch can be interpreted as a threat, and the reflex engages.

Tightness, then, is not only about muscle length. It also reflects how the nervous system is regulating movement. This is often most noticeable in the hamstrings, explored further in How Do You Release Tight Hamstrings?
