3 , 20, 40 and 不用加饭

Recently, I am making an effort to have a regular exercise regime.
It goes something like 3 laps around my neighbourhood (about 1.2 – 1.5 Km), 20 push-ups and 40 sit-ups on most of the nights.
I hope that it will make me physically healthier, and sleep better at night.
Also, I have been trying to eat lesser rice during meal times. I have decided that 1 scoop is sufficient, and I try to eat the dishes more instead of rice.
