you are knackered just after your workout because you have used all of your available energy lifting the weights so when you do the Cardio the only energy really that is going to fuel your Cardio is your fat stores just because you have no energy doesnt mean it isnt a good time to do cardio....

If your only going to mince along at a slow pace then after 30mins its not going to have much of an effect, but if your running like your a rapist on the run, then i think 30mins will nearly kill you and certainly start shifting that fat! |
it has been proven many times...if the fat falls of you after only doing 20min of cardio that is great but for long term fat burning it is better to walk at a steady pace of 3.5-4mph on a incline this taps into your fat cells much more effeciantly than running like an idiot for 20mins(the more you sweat does not determine how much fat you lose as some guys sweat more than others)..doing cardio between 65%-70% of your max heart rate burns more fat than going full out at Max heart rate for 20min....
but what you have to understand what works for you does not mean it will work for others for you to only do 20min cardio and the fat falls off of you i would say you have a fast metabolism....
also doing cardio on non training days means that you never get a break from training(weights/cardio)and you might fall into the overtraining syndrome....
