My favorite blogger recently resealed a new article which covers many subjects that might be of popular interest here: -anatomical comparison of the Federer and Djokovic forehands; -the straight versus bent arm debate; -amateurs and pros: differences; -the role of the wrist during forehands. The role of the wrist The author references a German publication on the role of the wrist, maintaining that this joint plays a two-folded role in tennis forehands: it both serves an acceleration and control purpose. But the most stunning part of it, at least to me, is that players like Federer and Nadal do not meat the ball with a very passive, extended wrist... the exact opposite would be true: Amateurs versus professionals The main argument the blogger makes is to the effect that "less is not more." Many people would argue that, unlike pros, amateurs will be bound to perform sub-optimal motions by sub-optimally sequencing sub-optimal movements and that, therefore, they should seek to simplify their strokes. The author goes the other way around the problem. In the world of pros "more is always better": optimal forehand motions are complex and they organize very subtle movements that are key to a good stroke. By trying to comply with the above advice of simplification, amateurs tend to do two things: 1- Get rid of certain movements -- often useful movement because they rarely can differentiate between what is essential and what is not; 2- Limit the scope of certain movements by restricting the degree of freedom of certain of their body parts. In other words, you're better off with an approximation of a professional stroke, with an imperfect execution of an optimal stroke than with a perfect execution of a sub-optimal stroke. I leave it up for discussion.
