Well I don't go to the gym but I lift bodyweight

how long have you been lifting? for 2 years with much breaks
what's your favorite exercise? I guess that must be the dips which I stopped doing because I can do much of them
what do you hope to achieve through lifting? I want to be physically fit for several sitations that might come in the future, also I don't want to get rusty and old.

I think sport is also important for the muscles because it charges the muscle in a different way. Not just single parts of the body be trainied and not really intensive, but more muscle groups will be aimed and slightly but constantly contracted.
