Movewell too good to be true?

Hello :)
I started with Movewell a few weeks ago as I am only 3 months postpartum and I was looking for short/beginner friendly workouts. I LOVE it there. Coach Nicole is amazing and motivating. I love the 30-minutes format; no excuse, I can always squeeze a workout in even with a young baby.

However, I’ve been wondering: it is too good to be true? Can you really get in great shape with this program? I feel like it can’t be possible since it’s so doable for me! I feel like even if I keep pushing myself with heavier weight it seems too good to be working long term. Any of you have had good gains? I’m hoping to become stronger and do a good body recomp after having my baby :)
