I am Ivar the engine driver/ toughing up without wanting to

[Paratus]

"Ivar the engine driver" has nothing to do with the post, I was just listening to a Who song and it was a line from it :D

Now to the real question, anyone toughened up a part of thier body without wanting or trying to?

For example, when I was trying to get break falls down in Hapkido I took a lot of flat on my back hits to the floor, those hurt ;). Now it seems the ribs in the back can take big hits, and I occasionally screw up a fall and hit my back it doesn't hurt much at all

This probably happens a lot in training but I was wondering what some other people toughened up when they were screwing up a technique :D

Yup, in a few places. The index finger on my left hand is twice as thick as it should be and I can't feel it when i bite it and my right leg is pretty insensitive to pain at the lower shin.

my calf muscles have become huge! I look like Popeye in a handstand!

My arms are definitely getting tougher. I don't necessarily get a bruise every time I get whacked in the arms, and when I do get bruises, they seem to be healing faster. I'm not "done" yet; there are still some tender areas!
