Alright I've been doing sets of push-ups, sit-ups, and then body-weight squats. I'm getting bored of the sit-ups and body-weight squats. The sit-ups because of the concerns/preferences you guys have posted previously and the fact that I'm probably still doing them wrong and will end up hurting my back somehow. The body-weight squats because they're, well, boring.
To review my situation, I don't have cash for a gym membership and I'm much more easily motivated to work out at home since it's "more time efficient" in my mind. Stupid, I know, but that's how I am for now.
What do you guys recommend that I add to my work out? I can probably afford a pair or two of free weights, some cables, and/or a pull-up bar. Though I'm not sure I want to install a pull-up bar in my house (not gonna lie, I'm at the parents' place to save on rent and I don't think they would want me to install one).
