Best exercises (besides weight lifting)?

[dawade]

So I'm not exactly satisfied with my physique and my stamina when it comes to athletics anymore. I used to play football and soccer and be able to run no sweat, but now even when I run for just a little bit at a time I am somewhat out of breath and have formed the beginnings of a beer belly...ALL OF THIS MUST STOP! So that's where you guys come in.

Without going to the gym, what are some of the better exercises and activities you guys can think of that one might be able to perform around the house?

Pushups, situps, running, swimming, basketball, and running football routes all come to my mind, but I was just wondering what you guys thought? I plan on swimming and stretching every day for a while and not eating as much (and eating healthier foods like fruits and veggies) to see if I can't shake this "gut" off before school starts.
