So I've been eating better and going to my Zumba class 3 times a week for a month , lost 12 lbs already... started at 172 and I'm now 160... I'm hoping to lose at least 10 more this month because I have a very huge and important family reunion and I want to look good with anything I decide to wear ... hopefully i don't lose motivation .. i haven't gone to the gym all week so I feel so bloated and yucky again 😔
