What does a kink (or double kink) on the downward side of the curve mean?
This shows that the athlete is not making the transition from back to arms smoothly. Power is being lost at the end of the back swing and the arms are coming in and increasing the power making the bulge. Try the sequence of exercises – legs only rowing for 10, legs and backs for 10 and legs back and arms (normal rowing) for 10. Be very clear that the athlete for the purposes of this exercise should complete each body part before bringing in the next one i.e. legs should go straight before starting the back swing. This is an exaggeration and not what you actually do in practice but it helps to illustrate the exercise and as the athlete gets toward the end of the 10 you find they will have blended the two or three body parts appropriately. Look carefully at the curves on legs only. When you move to legs and back the stroke curve should still be a nice inverted U but longer and probably with a higher peak.
