Why does the left arm of Roger Federer is different than the right arm?

Question

Haven't u notice his left arm is so thin..I wonder why...

Answer 1

because he hits right handed.. and he does not spend enough time weightlifting balancing the other arm to match.

Answer 2

Probably because he's right handed, he serves with his right hand and hits his shots with the right, so the left probably is a little underdeveloped because it's not used very much. I'm a righty and my right arm is definitely stronger than my left, because I use my right a heck of allot more than my left.

Answer 3

because he's a right hander...

like nadal as well... he's left arm is bigger than the right...

Answer 4

His right arm is bigger because he is a right-hander.

Have you seen the size of Nadals left arm because he is a left hander.

Actually Nadals left arm looks like a mature crab claw.

Answer 5

yeah..he is right handed player..so playing more with one arm means u develop more muscles in that arm..ur thickness actually refers to mass muscles in players' arms..

Answer 6

Because he's right handed.  When you make your career playing with only one arm, it's bound to develop more than the other.

Answer 7

Most likely it is because he is a right handed tennis player.

Swinging a racket like that with one arm for year is bound to result in an over development of whichever arm is being used.

Answer 8

nadals right-handed but grew up playing left handed fkn freak

federers arms obviously bigger coz he mostly just uses that arm in tennis.. one handed backhand.. common sense

hes also very flexible

Answer 9

All tennis players have that. I have it, my right arm is totally toned and hot and strong, but I have to work out with the left arm to get it to look/be strong.

Answer 10

maybe he only takes half vitamins.
