Research done on marathon runners and other endurance athletes who regularly partake in too
much cardio show the following characteristics including scarring of the heart muscle.

Kevin Lee really does not belong in the top 10 technically anyway in my view... he has
shown before, more than once, that he has issues making weight, he was not ready to take fights short notice, he does not have the
cardio (e.g. fight vs tony), and he does not have
much KO power either....
And the research
shows that there's actually not that
much difference in terms of 24 - hour energy expenditure in groups that take part in either moderate - intensity
cardio or HIIT, despite a
much shorter workout, low time commitment and lower total volume of training [3].
Research
shows that interval training is
much more effective for losing weight and inches from your stomach than slow
cardio.
Studies have
shown that increasing
cardio too
much can increase cortisol levels (which can be even more difficult for women with PCOS, as research has
shown that women with PCOS tend to have higher cortisol levels already), slowing metabolism, causing the body to hold onto more fat and more water.
I have been doing
cardio each day burning between 350 to 500 calories, depending on my activity, So it
shows my daily calorie budget as being between 1800 - 1900 calories on those days (which is pretty
much every day) I do my workouts.
Believe it or not, but research
shows that you can get a
much more effective workout in a shorter period of time if you are utilizing this type of intense interval training than you would with a long
cardio session with less intensity.
After all, research
shows that too
much cardio destroys your body and depletes vital fat - burning hormones like triiodothyronine (T3), growth hormone, and testosterone.
HIIT (high intensity interval training): Too
much endurance /
cardio work can actually rob your body of testosterone, while resistance training / lifting is
shown to increase the production of T, but this has a drop off point where too
much of either robs the body; a moderate amount of strength training and
cardio together make the optimal blend to produce T. Lifting more than three times a week can actually slow your T production way down, so don't overdo it.
