Bootcamps?

So, while I love exercising with my kiddos and wouldn't trade it for the world (after all, StrollerFit Akron/Medina is what allows me to get so much cardio and strength training in), I'm thinking I need a big push in grown-up-world-only for spring to really help me lose these last 8 lbs of babyweight and then focus on the 10 lbs more i wanted to lose BEFORE I got preggo.

I can't run with my little one in the front carrier ;-).

I still am breastfeeding through early March, and am not looking to begin until after that, but am starting some old fashioned R & D now.

Anyone have any ideas or opinions?
