So what drives me to roll out of bed at 5：00 a．m.？What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases selfconfidence and energy，extends life and above all improves my body shape.This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right.It's through commitment and sweat that I can make a difference within myself inside and out.
一个每天按时起床锻炼身体的女人，一个有着自己个性与喜好的女人，为了保持自己的体型，降低压力，提高自信，坚持着这种日复一日的锻炼，让自己每天都挂着笑容面对生活。
