Are Nadal and Federer too "heavy"?
Lets consider the builds of these players: Djokovic, Nadal, Federer, Murray, Del Potro.
They both seem to be getting a little bit slower, the question is, are they too heavy? Looking at the ATP website
Djokovic: 6'2" 80kg
Nadal: 6'1" 85kg
Federer 6'1" 85kg
Murray 6'3" 83kg
Del Potro 6'6" 84kg
In summary, despite being shorter, they weigh the most.
With the new generation, Murray, Djokovic, DelPo more attuned to "sports scientists", and other players like Roddick losing weight, is it time for Nadal and Federer to shed some weight, to gain better movement on court?
(Yes I'm aware that people will say muscle is more important, but the counter point is that Djokovic and DelPo are some of the biggest hitters on court today, weigh less, and are taller).
