why not do both?

Make ur pre work out and post work out be 15 to 20 mins of jogging which not only helps burn fat , lossening ur mucles but also elavates ur heart rate through an aerobic or cardio mode n prepares u for ur anaerobic workout such as push ups, weights and other muscular strengthening work outs.

1st, know how many cal ur body need a day, dont eat more than that. any exercise will do, as long as not excessive 1 cause u'll damage ur muscle

For me....in logical thinking....

Work-out = increase volumn of targeted muscle

Joggin = increase stamina/burn calories
Therefore , jog burn fat faster 

1st you will need to understand where does your fat come from , the way you eat ? family genes ? your lifestyles ?

2nd losing fat in different ways is sure lose no matter what , consistency is a must and hardship.

3rd looking at yourself which part of your body you would like to lose , fit ... start toning the part of your body and abit of other part of your body muscle

4th get a professional opinion and advice, learn from the seniors and work ur way to slim slim world ~

wat if i everyday over ate my meal n i dun put on weights? ?   

try this calculator, might not b accurate for asian http://walking.about.com/cs/calories/l/blcalcalc.htm

yes pre workout is 15 mins n post workout which actually helps prevent muscle aches be about 5 to 10 mins.

in between do ur anaerobic workout out for at least 45 mins, this is the best way to loose weight, build strength n maintain a healthy body.

remember, dont do excessive exercise, u'll damage ur muscle tissue more than it can rebuild. start with mild exercise, to get rid of fat to d level u want, another thing is ur diet, depends on what u eat

of course weight lifting. you can lose fat while gaining muscles.
