Hi. I have just recently started training (approx. 3 months ago), because I got VERY small and weak after lying 3 months in bed due to cancer and surgery.
I am already starting to see some real improvements in my muscular size, especially pecs, triceps and legs (legs, because of high-stress bicycling. About 25 mph average on a mountainbike 20 miles a day).
I however wonder, how I should train or/and eat, for slowly gaining definition, with the end result being something quite like this guy I borrowed from google:

I am also quite annoyed by my ribs, they are always visible on me, even if gaining 10 pounds additional weight (which hurts my stomache and eyes...). I don't know if you would know of any possible reason for that? I have almost too low body fat though.
And at last, what should I avoid, if I do not want to look just bulky, like this guy:

Thank you, beforehand
