Not a YouTube channel and there is a cost to it but I use the Courtney black app for home workouts, there are multiple trainers on there. Frilly has left now but her prenatal yoga on there is 💯 and Rachel does pre/post natal specific workouts ☺️
I swear by yoga with adriene!’ She starts tight from basics and has a refreshing touch!
I do online classes if you'd like to join something live :)
Boho beautiful on you tube has pregnancy yoga/pilates 👍🏻
