Hey girl.. I have almost the same weight and height as u. Been working out since last month and
cut dw my dinner and supper. I used to work out in gym and drink protein but I realized I m building up muscles thus I stop all those strenuous weight lifting. What I have done for this month is: 1) went for early jog at 5am around 4km 2) went for dance class everyday if possible 3) pingpong or badminton training twice a week 4) swim occasionally and I lost 3kg in this month!!!!

that is because she had yet to post to a proper reply on her WORKOUT routine and diet plan. Look at how vague her answers are. Initially I kept stressing GOOD TRAINING ROUTINE AND DIET PLAN , eventually I just gave up because some one liners came out of nowhere cheering her on with what she's doing now which is a big mess.
Let me get this across VERY VERY CLEAR, you want to lose weight ? Weigh train, choose a proper WORKOUT routine and stick with it. Darklight has mentioned it somewhere about studies where you can run like headless chicken for so long and burn so little, stick with weight training, the calories burnt are way over the top and you rev up the metabolism crazy. You wanna burn fat? Rev that metabolism.
Why do I say choose a proper routine, because you haven't got a clue about what you're doing considering your reply. Stick with weight training BECAUSE they incorporate movements, COMPOUND movements. The more muscle fibers gets utilize the more GH one will have released in the body BUT at the same time, THE MORE MUSCLE FIBERS gets utilize THE MORE CALORIES you're going to burnt.
Your personal belief on the total package including crunches is only right to a certain point, you think crunches will give you abs? Yes, BUT not doing them will give you abs as well , just ask Darklight. It's all about dropping bodyfat levels, not a million crunches a day. And let this be very clear, you can build as much muscle as you want, but if you don't drop the body fat level, there is only so much toning you can to your body. The reason women you admire so much are so toned up is because they train hard, eat good , rest well, BUILD MUSCLES AND DROPPED THEIR BODY FAT LEVELS. So aim for that.
And eat properly if you want to lose weight, one CAN NEVER OUT TRAIN A BAD DIET.
Aim for 5 - 6 meals a day of SLOW DIGESTING CARBS and LEAN PROTEIN and GOOD FATS. Have a cheat MEAL not DAY once every week or so. You want a toned up body, you need muscles, SO FEED YOUR MUSCLES. Don't try to reinvent the wheel, keep things simple , follow this to the T and you will achieve what you want.
It was meant for the TS but you mentioned about when having confusions to message me in the pm, follow this staple. You don't have to do exact but it's a good bare bone guideline to go with and I also explained about why to do this and not that as such in the quote.
