I don't. And I hate it.
My main exercise was riding with some walking, swimming laps with DS in a boat that I would use as a kickboard, pilates, and ab work. Well, riding? That's out now. Pool? Closed. Abs? Nope. Pilates? Too much strain on abs.
In the AM DS has various classes that we both attend so morning walking is out. Then comes lunch, then the nap, then errands or the playground or whatnot, and then I'm making dinner, and then I'm passing out between bites.
I also worked out when I was preg with DS. Walked almost 5 miles daily with ankle weights. Now? I'm 10 weeks along and nothing but flab already. And I worry that this baby won't be as healthy.
I'm looking for solutions too. OH. And can I mention that DS HATES his stroller and I get too dizzy with him in his ergo? So I can't even pop him in there and walk.
