RM 300 a month = Herbalife

RM 300 a month = Good clean healthy food, maybe a membership at a reputable gym or fitness centre which result in a more permanent and healthier phase of weight loss, AND a sense of achievement that you lost weight through your own hard work.

Do the math.

Yeap missy. Ya ain't alone, lemme tell ya that. I appreciate a woman who can leg press and squat a respectable weight. They need to get the ridiculous notion outta their heads that lifting weights will build muscle. Women don't have sufficient testosterone for Christ's sake.
This is why a huge percentage of women fail in their weight loss goals. They lose too much healthy weight, too rapidly, which mostly consists of lean muscle mass. Lean muscle mass is responsible for elevation of metabolism, hence greater fat burning.
This is why weight training will always rule over long duration low intensity cardio.
High Intensity Interval Training which is another form of cardio is another matter but i won't delve too deep into that.

I assume you're a fitness buff yourself?
