Hey gang, Some friends I keep up with through the Internet have been telling me of their amazing progress over the past year or so with weight training. Now, I'm a poor graduate student who's really strapped for time and can't make it to the gym. I stay busy, but I'm trying to come up with ways to get a little more fitness-active at the apartment. I know I can stretch, jog in place for some cardio, and do various combinations of situps and pushups for overall upper body. Does anyone else have exercises to contribute?
