Update.

If you dont do squats correctly, u can really fuck up your body, especially your lower back. Im not a big fan of them, if u already didnt know, but i love doing leg workouts. Still, doing heavy weight is only going to put on more pounds. Do more reps of lighter weight to tone first, then when you are comfortable where your at, start increasing weights and decrease reps. The main goal though is to lose belly fat, which is not the easiest thing. The cardio wil be good, but doing ab and lower back work is very important as well. A leaner mid section will not only be good for running, but for your overall health as well.
