Excercise after pregnancy!

Holly • 25, due with our first baby(boy) December 29! I've been married (to the best husband) for a little over 3 years now!😁
What kinds of excercise are you mamas doin to lose the baby weight?! I used to run 5 miles or so before my pregnancy so I'm trying to get back into that! But did t know if there was any good workout tips!..:)
