Thread: slow cardio?

i beg do differ bro, studies show that at short periods of high intensity cardio are equal to longer less intense cardio sessions.....the reason the intense sessions are short is to prevent your body from tapping into protein within the muscle...jogging for 30+ min will cause a muscle burning effect, studies also conclude after 7-10 min jogging a persons body taps into the fat stores for energy, giving 10-13 minutes of rapid fat burning, you can do what you want to do, if you get bored easily jog for 20 min, if you love walking on a threadmill for an hour go for it...and no 20 minutes of jogging will not burn Muscle...

Happy New Year! Welcome to all the new subscribers to the HotBod newsletter as well as those who have been with us from the beginning. Each month we'll explore issues relating to the three major areas of fitness: exercise, nutrition and supplementation. As always, your comments, questions and suggestions are always appreciated.
TRAINING CORNER: Cardiovascular Intensity/The Right Speed
This myth was given credence when several research studies indicated that low- intensity activities burned a greater percentage of fat calories than high- intensity activities. These studies validated that the body prefers to use fat as its fuel source during low-intensity exercise (equating to roughly 60% of the calories burned, as opposed to about 40% from high-intensity exercise).
However, it is misguided to believe that the selective use of fat for fuel will translate into burning more total fat calories. High-intensity exercise burns more fat calories on an absolute basis than lower intensity activities. Since the most important aspect of training intensity is the total amount of fat calories burned-not the percentage from fat-higher intensity exercise has the decided edge.
Furthermore, when you consider the time related efficiency of training, low- intensity exercise provides a very poor cost/benefit dividend. After all, why would you want to spend an hour running on the treadmill when you can get better results from training for half that time? In final analysis, if fat burning is your aim, performing cardiovascular exercise at a high level of intensity is your best choice.

hit cardio helps burn fat for longer after you get done, just like weights where you grow outside the gym not while doing the lifting, you want your cardio to burn fat all day after you go home
