I highly recommend the Beach Body on Demand app/subscription. There is a workout in there for anyone plus you can shake things up whenever you want if you feel like your workouts are getting stale. Honestly, going to the gym is the WORST.
I did do Insanity back in the day, still have those downloads somewhere. Have moved on to a program specific to pregnancy/post partum and love it. Been using it for just about 5 years now. If you have pregnant/newly post partum women in your life send them my way and I'll evangelize lol. Developed by sisters who are a women's PT and an exercise science grad/nurse. Made to prevent all the mom aches and can fully vouch it.
I like growingananas on YT as well.
