Packed Schedule!

My week seems to always be jam packed these days! First of all, as I discussed in the last post, I picked up a new job Mondays and Wednesdays hosting trivia. On Tuesdays, I participate in pub trivia with my regular team (this, by the way, is how I got the job in the first place.) In two days, my regular Thursday night bowling league starts back up. Obviously, this leaves my old plan of exercising after work a little undoable. Obviously, this puts my weight loss goals back a bit.

So I've been trying to exercise at home. For example, before I eat dinner I always try to do some push-ups (about 20) and air-squats. Allegedly, this helps put the body into gear for using rather than storing the calories it is about to consume.

Also, sometimes on the weekends, I like to just kick it and watch DVDs or play video games. I've been doing a set of my work out between each game (so about 1 set every twenty minutes) and probably 2 or 3 sets for each hour of TV I watch. So far here is what I've been doing:

-10 push-ups
-30 sit ups
- 25 15 lbs bicep curs
-20 air squats

Obviously, this doesn't work out the whole body,  but I figure it is better than nothing. So I'm looking for suggestions here. Are there any other great quick exercises i can add to these standards?
