Hey Guys recently I put up a poll to see if you guys new whether it is a good idea to do Cardio to burn fat. Well the answer is yes and no. Cardio is great for your heart and respiratory system but its not the most effective way to burn fat. If you would like to burn fat fast your work outs should be like this. First your should do a normal super set work out for about an hour then after wards jump on a Cardio machine (I recommend the treadmill) then do a 4.5 mph walk for two miles with an inline of 4.0, this will take about 28 minutes. It is a little annoying to do this at first but soon you will get used to it after each of your workouts.
