Vidic is pretty lean, tbf. Certainly far more so than the tubby Pikey.I am not sure you could attribute fitness only to muscles and Cuts tbh.
The basic body physique and Genes differs from country to country and region tbh and obviously player to player. Sachin has never really had a muscular frame or cuts but that hasn't really hindered him too much and he is one of the hardest working players.
It's a natural physique he has that is a bit like say Wayne Rooney compared to the cuts of Cristiano Ronaldo or a Nani who have massive muscles and Visibly toned bodies when they go shirtless.
And with the added difference that for a batsman in Cricket it is not as important to have pure muscle as it is for a footballer.
But before we digress too far, I'll say bowling fast is comfortably the most physically demanding discipline in the sport. Fat seamers tend not to last too long.
