alright girlies

I'm starting the Paleo diet this week🤗. I need some beginners work out routines. I have a 2 year old so nothing to the extreme. I'm getting a planet fitness membership in March, but I want to get a head start at home. What works the best and what is the most fun? my goal is to be at 120 by the end of this year. I'm 5'1 and 178 lbs.
