<human>: Can you provide a brief overview of the text?

Hey there, not sure if this is the place to ask this but I have been trying to diet on and off (I know, I need to just keep at it and excuses are not a reason.) But lately I have been going to the gym with my friend which has helped me quite a bit getting exercise in. However, yesterday I noticed something. 

When I started 2 or 3 weeks ago, my squat max was quite pathetic on what it was compared to in high school. In high school I was maxing out at 285lb when I weighed 115lb. I think my squat max 2 weeks ago was somewhere around 180. But yesterday, I somehow manage to get that up to 240 pounds. Which makes me think that I don't have any fat in my legs, which also made me conclude that I don't have much fat in my arms either. 

I think all of my fat resides in my belly and on my back. I currently weigh 165 pounds (I'm 5'3" so I am short) and I am attempting to get down to at least 130 by the end of the year. I know it's not much to lose, but with my eating habits and my love for video games doesn't help much, it also doesn't help that my friends and family live so far away so I can't play any soccer with anyone around. 

Anyways, so my question to you guys is do I keep going to the gym and weight lift? Or should I be doing more cardio with dieting on top of that? Any help would be greatly appreciated.
<bot>: Started weight lifting with friend, realized I only have fat in stomach and back, need to know if I need to change exercise to cardio and dieting.
