I followed the video here > http://www.youtube.com/watch?v=vkKCVCZe474
My neck felt pain when doing the activities and still feel a little tension on my neck part. Is this normal? o.O Will it affect my backbone.

I tried doing my best. Probably I'm using my backbones not the abs. So how? ><

Hm, then what should I do to "focus on my core"?

Can I put my hands on my chest? So I don't have to put any pressure on my neck.

I see. I was doing that on a wooden floor, anymore suggestion?

What are the things to reduce my fats? Drink more water? Cardio activities like running?

So if I eat like chicken, fish and other things other than bacons-like-meat will be better? Are there any more exercise which doesn't require equipments?

So should I like stop eating meat or just avoid fatty meats?

Alright. But thing is my area here not suitable for running

Then what other HIIT exercises that I can try? Other than running?

@Kasey Brown, so should I do crunches, overhead presses, front squat or HIIT or..all? XD
