I'm new to this forum, and I joined because I want to get some more definition and well...have a firmer tush.

I'm not all into lifting weights so, I've done everything from aerobics to tae bo, to swimming, jogging, biking, and so on and so forth. Thing is I get bored quickly and need something new.

I'd like to know your take on this, if they work, if they're good, if they indeed burn fat and help me get a fit(er) body and so on and so forth.
