A controlled way to learn body wave, blade timing and a stable streamline.
Start from the trunk
Efficient movement travels through the chest, trunk and hips before reaching the blade. If the knees lead every beat, the fin may create drag and the lower back may absorb unnecessary load.
Use short, observable repetitions
Practise body wave without equipment, then with support, then over a short distance where the coach can see the full line. Rest before fatigue changes the pattern.
- Keep the head aligned rather than looking forward constantly.
- Allow both the downbeat and upbeat to move water.
- Reduce blade stiffness if control or ankle comfort deteriorates.
- Stop for pain; do not force range through the lower back.
Speed is an outcome
Tempo should rise only while the wave stays connected and the swimmer can stop safely. Video feedback can help identify excessive knee bend or a broken streamline, but it should be interpreted with a coach who saw the attempt in context.
