Flat tummy excercise (at home only)

I have recently made a pledge to stick to my new routine of carrying out my tummy work outs everyday. I ran into this video and has been helpful. I must confess I have been writhing in pains ever since I began these exercise on Saturday but its worth the effort.

I follow the steps after steps and I push myself to build my tenacity.

Who knows? I might one day become a fitness instructor.
