The only way to build muscle is to put that muscle under stress. Pushups and situps sound ideal for you, and biking will develop the large muscles in your legs. Did you mention if you can get some weights for your house? And if you have belly fat, you're still fat and need to lose more weight.
I don't think it's so much fat as just my insides leaking out through soft, worthless muscles.
I realized yesterday that simply standing up completely straight made the pot belly disappear, but also made my back and stomach muscles quiver from all the work. Which indicates that my core is just a touch weaker than a very small baby and my posture sucks.
Got used to being a fat slob because of my knees. Going to fix that.
