(Ignore the wrong title for topic. Dx)
Okay so current:



What I want:


Not exactly like that but something in that range.
(yes, I know my body type is different than this person)

More or less, I'd like a flat stomach with some definition.
I have the definition but I don't have the flatness. :\
Any advice would be great on how to achieve it.

Info about my diet:
I'm totally broke 90% of the time so I usually eat once a day.

1. I heard running helps but it's far too cold for that.
2. Can't join a gym or purchase equipment.
3. I have lots of space and 2 15lb weights at my disposal
