When an adult comes to a first class, they nearly always mention the same thing: “I am not flexible.” Usually that means they cannot touch their toes, and they assume the answer is more stretching. The answer is often something else.
What flexibility actually is
It helps to separate two things. Passive flexibility is how far someone else, or gravity, can push you. Active flexibility is how far you can move yourself, under control, with no outside help.
For Kung Fu - and for everyday life - the second one counts. A kick is useful to the height you can lift it, not the height someone can push it while you sit on the floor. For most people the gap between those two numbers is large, and that gap is where the real progress is.
Why passive stretching is not enough
If the body has no strength in a new range of movement, the nervous system will simply not let you into it - not because a muscle is too short, but as a safety measure. That is why people stretch the same muscles for years without lasting change: the range gained disappears within hours, because the body has no reason to keep it.
The body keeps only the range of movement in which it knows how to be strong.
What works better
- Loaded positions. A low stance you hold teaches the hip and ankle to be stable at their end range. That is a stretch and strength at once.
- Active raises. Lifting a leg slowly, without swinging, teaches the body to use the range it already has.
- Movement through the full range. Joint rotations in the warm-up are not a box to tick - they feed the joint and signal that this range is in use.
- Breath. An exhale during a stretch releases tension that strength cannot overcome. It is the most underrated tool, and it is exactly what Qi Gong brings.
What about the splits
The splits are impressive and useful in some arts, but they are not our measure of progress. A high kick is a consequence of hip mobility, not proof of it - and for self-defence a low kick is almost always more useful. If the splits appeal to you as a personal goal, fine; just do not mistake them for progress in the art.
How long it takes
Training twice a week, most people notice a change within three months - first in the hips and ankles, then in the shoulders. Lasting change is measured in years, not weeks, and that is actually good news: it means it lasts.
At Body.Mind in Ljubljana, mobility work is woven into every class rather than saved for the last five minutes. It can be adapted to any body - including one that genuinely cannot touch its toes today.
