Lying down
The learning position
Lie on your back with your knees bent and your feet flat. Let your lower back rest comfortably. Put one hand on your stomach so you can feel whether it tightens. Squeeze the pelvic floor gently, hold for a short count, and release fully.
This is the easiest position for checking technique because you can feel the difference between a clean squeeze and a brace. Many guidance pages recommend keeping the thighs, buttocks, and abdomen relaxed, and lying down makes that instruction easier to follow. Stay here for your first week if you need to. There is no prize for moving on quickly.
