I started exercising regularly since two months ago, the reason is not because of a growing trend today: all about gym and fitness things, including Muay Thai, Yoga, TRX, etc. which is you can see, it's now a lifestyle, after fixed-gear bike and running. You'll realize if you are Indonesian, we are very talkative people when some western stuffs branched out then we will follow BUT in relatively long time (telat gaul). Bahahaha!
I feel sorry for myself that I just realized that exercising is an important part of life, especially if you're working. Energy can be discharged in the workplace, including your brain. The brain constantly forced to work, resulting your body would feel so tired easily. That's why we always run out of energy for a brand new day (and we rather choose to sleep during holiday).
