Hi guys, I'm looking for some home fitness ideas. I used to get most of my exercise through bike commuting and racing, but since I started traveling there's just not enough exercise built into my daily routine. I do walk a lot and still ride occasionally so I think I'm fine on cardio (and I don't want a heart attack, hah). I feel I ought to add in some resistance training for overall fitness. I've been doing nifty nines fairly regularly since high school so my abs are strong, but I'm clueless otherwise. I'd like to do exercises not requiring equipment as I don't have the space for anything heavy / bulky while living out of my car. Also, I've had surgery on both my elbows so I can't do tricep movements like pushups. My other arm muscles are fine, but very weak. I have difficulty lifting moderately heavy objects and I've never done a pull-up in my life! Ideas?
