Wow guys - thanks for the great advice !

I'm going to try each and every one of these exercises, they all look great. As for the losing body fat - I've taken up running and have been making a conscious effort to change my diet (although admittedly, that's been slow going - why does everything that's so bad have to taste so good?! I'm working on it though

).
Just a quick couple of questions. I don't really know much about exercise terms besides the very simple ones, so what exactly is a "fly"?
Also, for the ab raises - do I pull myself up with my arms as I pull my legs up? (haven't tried this yet, so don't know if that's physically possible or not

) Or do I just dangle there and raise my knees?
Thanks again for all the help!
(oh and hobo - i've used the monkey bars as pull-up bars before too - make sure they're wide enough i guess hehe)
