postpartum work outs

What are you mommies doing? I'm 5 weeks & 2 days postpartum, stopped bleeding at 4 weeks, so I'm going to start doing light walks on my treadmill! It's too cold/snowy here to take kiddos on walk outside unfortunately or we would do that too for the fresh air 😔 I think we may make a Walmart trip next weekend to get some weights & a few other things for after my 6 week check up before I introduce those into my workouts.. I'm extremely interested in the peloton but it looks super pricey 😭 also, I'm strictly breastfeeding so don't know how working out will affect supply or even if it will? i dont know..
