Possible to get a 'Beach body' by June or July?

I am the same height and weight as you, and about 30 years older! Exercise for your health, set good exercise and eating habits, stretch, pick up some weights and get strong, it really will help! Your body will change many times in the coming decades, and good habits will help get you through the highs and lows. You are young and yes, you theoretically can get to your ideal weight by mid-year, it's just a number after all.

If you want to wear a bikini-do it. Own it! I know I will be!
