Well now you start doing crunches. It help improving your appearance. Takes weight off you spine. Help you do other work out better.
You got think like an athlete.
I always drink water before eating, None during or after. Even when I don’t do tummy work out muscle stay in shape. (ITs sunnah too)
Now as I said before. You need to ad more to your work out. If you do say stairs over 20times. You are going to feed your self some protein too!!!
By not having a good breakfast you miss best part of your day. I think its few hrs after breakfast when your brain works best. Whit no breakfast you just miss it.
So I say less carbs more proteins and more work out. Try gaining some muscle mass now.
Now we have most of things layed out.
Next time post your work outs.
exact timing of walking/running.
Time you climb stairs.
Crunches.
