cutting fat
To cut fat you need to burn more calories then you eat, period.
So burn some more calories.. using cardio is fine.. whatever works.
But what is easier.. is decreasing your calories.. cut out any soft drinks with sugar.. cut out mayonaise and dressing.. these little things can add up to HUNDREDS of calories per day. It takes running a mile to burn a hundred calories.. so think of it like that.. I can drink this soda and run 1.5 miles.. or I can drink water and just hang out.
