Lifting 'high reps and low weights' is not a part of anything other than resistance training. Are we confusing muscle toning exercises with fat loss here?
The duration of a a resistance exercise isn't long enough for your body to have to use your Aerobic system which is the only system that uses fat as an energy source. You'll be doing well to be using the Lactic system for half of it... ATP-CP is what will primarily be used.
The only exercises that are good for targeting fat stores are low intensity, long duration rhythmical exercises that recruit large muscles groups.
Long duration isn't the amount of time it takes your lactic acid and ATP-CP systems to fatigue... by the time you've finished your set they're already resynthesizing ATP.
