Srinath,
Mate your pattern sounds fine,which makes me wonder what could be missing?
Are you performing the excersise's in the right manner? Specially while doing Abs breathing does matter!
Tell me how long how you been following this excersise & diet pattern?
Moreover,along with your excersise I would suggest keeping away from the following atleast / until you find results:
1) Soft drinks - Strict 'NO'
2) Pasteries / any bakery item a big 'NO'
3) Curd rice - plus you may reduce your intake of rice to just once a day preferably just for lunch.
4) Ghee / Butter
5) Bread / Bun
6) Biriyani / ghee rice
7) Juicy chicken / kabab's - rather reduce in take of non-veg include more veggies & pulses.
8) Bananas
9) Reduce intake of Tea / coffee [If you can't go without it just have 1 cup a day]
Instead try & take black coffee without sugar, it does help but i would suggest dont make it a habit just take it for a month.
