how and by which activity did you restarted to exercice for the first time whilst recovering?
Stretching, yoga, running...?
   I first began with going for 30-60 minute walks with my dog 2-4 times a week. And then when i was 2-3kg from my goal weight i was allowed to begin running as that was something which i wanted to begin with again. I was only allowed to run 30 minutes 2-3 times a week (instead of a walk) and of course had to eat more. Then i began going swimmin 1-2 times a week and then i tried dancing, and then i finally bought a gym card!! 
   ^^ I didnt do all of that at the same time, i.e walking, running, swimming and dancing. I exercised about 3-5 times a week when i was allowed to exercise more regularly!


How do you feel about leg muscles (muscular calves, thighs)? I´m afraid to start running because of the leg muscles growth.
     You really shouldnt be scared of that. If you enjoy running, then you should run. Running helps tone your legs but of course it makes the muscles stronger.
   Before i used to hate my legs, they were one of my problem areas. They were always too big in my opinion, and took a very long time to accept, espcially because while i was underweight i had a thigh gap but the thing is, my body shape is not meant for that. I dont have the biggest hips, so naturally i dont have a thigh gap. And thats fine with me! I dont need one.
   Now however i am focusing alot on my legs, making them stronger!! Trying to tone them, and they will become 'bigger' as i gain more muscle, but thats ok :)
   You should focus on accepting and loving your body, not so much about how it looks. Because your body will always change... and there is not so much you can do about it. You have to just love yourself at any size, and the way you look otherwise you will never be happy!
