Monica, what a great job!
Actually getting to a gym with full-time care of triplets, that's pretty impressive, too! And I think you might give your body some credit for being amazing enough to bring those triplets into this world; so many people could never do that! Still, being trapped in a body that doesn't reflect your verve and energy - we've all been there, and some of us still are. Your feeling so much better after 16 lbs lost, is going to be inspiring to a lot of us just starting out, I think! Not to mention being under 100 lbs left to goal....
Isn't it wonderful, when friends notice? Get used to it, you're about to get flooded with more of that, just keep going, girl!
