Why do Rugby Players have harder balls than other guys...?

Question

Okay... here's a weird question... me and my two friends all headed off with Rugby Players not too long ago and all three of us noticed that their balls were harder, almost like ping pong balls, than usual guy's... we didn't know what to think of it and still don't know why they're like that... is it because of the training or so? Thanks in advance!

Answer 1
