I'm a seventeen year old female. I had a moderately active childhood, but I've become very idle in the past several years (since 13 or so). I think the main reason why this has happened to me is because of stresses from other aspects of life (school, family problems) and the fact that, well, I have a pretty "ideal" body type. In fact, I haven't gained any weight since I was 13. In short, I'm rail thin. I'm not complaining. I'm very happy with the way that I am, but I would like to be more in shape and maybe have some defined body parts (I don't show my arms or legs ever).
I've always wanted to be a runner. For the past two days, I've been walking around my neighborhood (roughly 1.5 miles). It takes me about 25 minutes, but at least I'm walking. But I am very sore in odd places. Like the top part of my ankle (that faces the tongue of my shoes). I usually wear high heels, so I think it could be because I'm not used to walking flat footed? Is this normal? And the area of my leg from the back of my knee to my thigh. Am I walking "wrong"? Is there anything I can do to alleviate this?
Is walking like this even going to do anything for me? My family is not very active with fitness so I don't really have a role model, so to speak, to base anything off of. I don't even know where to go from here, other than the fact that I'm actually moving my body. Haha.
