Why all the injuries? It seems constant. Just one more indication that the Williams' sisters, aside from having poor coaching, don't seem to be preparing their bodies properly for long term, high intensity tennis matches. Serena is down--AGAIN. Venus is always complaining about something and often hurt. Why? These are young ladies. Why have the great champions been able to play year after year after year and hardly ever go down? Yet these ladies are constantly injured, and for long stretches of time. Clearly, their training methods, overall fitness regime, not to mention their coaching (they have not improved at all, if anything they've both regressed, especially Venus) need to be called into question.
