Oh and congrats on your little one. Happy Mother's Day!
It is hard! And you have to keep at it - but you will improve. I use it to cross train with step and kick boxing and everything else we do! I carry all my weight in my butt and thighs and I feel it helps tighten my thighs. It's like all workouts, you have to vary how you do it. I have Spinervals and Cardio Coach that I use with it and the workouts are steady state, intervals, some standing, etc. So quads are a focus but when you're doing hard cranking vs fast spinning, I feel it more in my hamstrings and glutes. Go try it!
So, no standing up while peddling, I imagine, though my kids seem to do it all the time (I feel like I can imagine it tipping over if I tried). Did you think I could stand and pedal? Maybe I should just try it. Somehow when it's a cardio coach day, I want to go outside and run, but maybe I should give that bike a whirl..... I could use tightening up in the lower half.......
Laura, well, my "regular" stationary bike actually is a recumbent!

But I do think when you increase resistance you get a good quad & glute w/o. 
My opinion is it hurts b/c it left bruises on my butt.
Beth--have you ever tried a recumbent bike? I think b/c of the different position it might give a better leg w/o than a regular bike. I'm not a spin expert so those who are please correct me if I'm wrong, but I think a lot of the leg work comes from when you're "standing" on the pedals--i.e. butt is off the seat.
