The weight you are now is perfect for your height. I wouldn t recommend losing any more but if you just want to be healthier in general, then what you re doing is fine. And no, you won t lose your boobs. That only happens to people that are extremely overweight that lose it.
If you re just getting leaner, I don t think 5 lbs will effect your boobs, so your e okay. Just remember to wear a sports bra, to prevent stretch marks and sagging/drooping of breasts. I made that mistake, half the time I couldnt change my outfit when I exersiced, I m working on getting it firm againIt s just about getting fit and being healthy anyway
3 k in 30 min is a really really really poor effort, you should try running 3-4 miles in 30 minutes!!!!
ya u gonna lose ur boobs alright
