Oh, those photos are so bad. Seriously, looking at them hurts my eyes.
You single by the way?
hehe!
I know this might sound scary to you, but have you considered weight lifting? If you have any concerns regarding this, just ask. To be honest, I don't know what you are trying to do here.
You are basically asking us how you could tone your already toned stomach.
I see no fat and I see abs. You are toned.
I think what is going on here, mostly, is that you are bored. Weight lifting with a partner, perhaps? Sign up for a marathon and train for it? Join the local martial arts school?
