Look out Venus and Serena!

Or maybe not.
Erica and I recently were discussing over e-mail about whether or not your thighs get bigger because of spin.
I have noticed recently that some of my pants seem tight in the thighs (pretty much all of my pants are tight in the butt area–that has always been an issue for me since I have a big butt and hips). And I am still on track with my weight maintenance.
I did some research online. I found some sites that said your thighs and butt do get bigger with spin. And others that said that wasn’t the case.
So I went to my best source, my spin teacher, Jennifer. She says your thighs don’t get bigger because of spin. Yes, they can get more muscular and toned, but not bigger. She didn’t have an answer to why some of my pants are tighter in the thigh area.
So, hmmm. Wonder why our pants are tighter?
