That Guy

hi guys, first time in this thread (I think) just want some advice here. I've got a 3 year millitary service which starts in July, except I'm not as "big" or "bulk" as I would like to be. I had a few month membership for a nearby gym but it's very expensive and I'm wondering if going and doing "around the house" stuff will have the same effect or will I have to find a way to get a renewed membership? By "around the house" stuff I mean- pushups, situps, maybe getting myself a chin-up bar in the doorway when I enter the room, possibly pushups with a bag on my back with books, runs around the area... What I'm asking is will I get the same effect or do I need to go to machinery in gyms?

Thanks in advance.
