I'm 19 and in half descent shape maybe a pound or two overweight I want to tone my muscles and get some abs to show. What types of exercises should I do and what's good diet to eat while on that exercise routine. I've tried going to the gym. I went for about 4 months once every other day and was able to do about 250 sit ups but my stomach had 0 abs looked fat still. And my arms got strong but didn't show so I've stopped going for a while but want to try again but with something that might work and please no bs pills or machines that magically change stuff.
