Getting back into the swing of things!

Hello! I was a part of this before but I slacked off for a year or so. Now I'm ready to jump into this and give it my all. I have a great reason this time: I'm going on a cruise in October and want to look my best! My biggest thing is not being motivated so I need all the support I can get. I'm 21, 5'2, and any tips/workouts is greatly appreciated! My end goal is 15-20 lbs but if I can lose 10 by October I'll be happy. Feel free to add me! I'm looking forward to meeting new people.
