Increasing Testosterone Through Weight Lifting and Weight Training
Iron. That's what you need to take to increase your testosterone. No,
I'm not talking about the mineral - I'm talking about something you lift
off of the mat in order to build Muscle. There are actually studies that show that
testosterone can be increased simply by lifting weights.
Now, before I go on, let me mention that there is a transient boost in
testosterone that occurs whenever you lift weights or do strength training.
The bodybuilding magazines love to make a big deal of this. But they
shouldn't since this "increase" in testosterone is for the most part nothing
more than a subtle increase in "hemoconcentration" of your bodies testosterone.
In other words, during a workout your body is not flooding your system with
testosterone as these magazines would lead to believe - quite the opposite.
So then why do I say that weight lifting leads to an increase in testosterone?
Because there are several studies out there that show that patient and
consistent - I emphasize the year-after-year kind - weight lifting slowly raises
baseline testosterone. And I hope that grabs your attention, because it is
baseline testosterone that we want to increase. Baseline testosterone can
be thought of as your testosterone "smoothed out" and probably the best measure
of it is early morning testosterone. Your testosterone, unless you've got
a nasty sleeping disorder, peaks in the early morning hours and then tapers off
until evening where it hits its low.

Natural Versus Testosterone Therapy
One fairly recent short term study of 8 young men with an average age of 17
showed significant increases in baselines testosterone (7.5%) in only 11
weeks.  This is a nice increase in testosterone when you consider
that it occurred in less than three months! What did these young pups do
to increase their already abundant testosterone? They simply engaged in
"explosive strength training" for these 11 weeks.
Are there any studies showing
that this exprapolates to longer time frames? Yes! One study of nine
elite weight lifter over a two year period showed significant increases in
testosterone, leutenizing hormone and the ratio of testosterone to SHBG. 
The authors concluded that "the present results suggest that prolonged intensive
strength training in elite athletes may influence the pituitary and possibly
hypothalamic levels, leading to increased serum levels of testosterone".
Yet another study showed that elite weight lifters had significantly higher
testosterone levels than elite cyclists.  In other words, the body
seems to adapt to the kind of exercise placed before it. In everyday language that means that weight lifting and weigh training very
likely lead to increases in testosterone over time. Remember that
testosterone seems to be increased by any competitive challenge in the short
term. The amazing news is that hitting the weights seems to imprint itself
in our glands and force them to spit out more of the precious stuff.
As a side note, one 2008 study in the British Medical Journal had an interesting twist: it
showed that those with greater strength compared to those with weakest had a 32%
reduced death rate from all causes.  This is an incredible reduction,
especially considering they are just looking at one factor isolated by itself.
Even more remarkable is the fact that the results showed that there was a 50%
reduction in heart deaths and 32% from cancer. So weight lifting should pay
huge dividends in more than just increased testosterone levels.
CAUTION: Before, I got on I have to issue a caution here: you must be careful not to
Overtrain or you will whack
your precious testosterone instead of increasing it.
Also, one question that may have crossed your mind is if these results translate
to other sports and methods of training? Well, we don't fully know the
answer to that question. What we do know, though, is that long endurance
sports such as cycling seem to lower testosterone in the same way that weight
lifting and weight training seems to increase it. For example, one 2003
study "that basal testosterone levels were significantly lower in cyclists than
age-matched weightlifters or untrained controls".  In fact, some
researchers have actually concluded that this is an adaptation that gives
cyclists and other endurance athletes a
competitive advantage since, after all, testosoterone and it's ensuing muscle
mass would probably slow them down.
So should you lay off of all endurance sports? Well, I would be cautious in
making any such rule. Remember the incredible Power of Exercise. Exercise
decreases heart attack risk, improves your risk of dying from all causes, lowers
inflammation, improves your erectile strength, protects your brain (in a dozen
ways) and, above all, gives you endurance in the bedroom. So, if your
testosterone is in a halfway decent location, you will almost for sure not have
to worry about a small drop in testosterone that comes with any endurance sport.
If, on the other hand, your testosterone is low anyway, then you need to be very
cautious about lowering it any further with a triathlon or marathon.
Remember: the Symptoms
of long term low testostone are nothing but ugly and dangerous. Rememember you
want to increase your testosterone if need be in order to increase your mental
outlook and attitude as well as build your lean body and muscle mass.
Testosterone does all that for you: there is no substitute!
NOTE: Taking Cialis (or probably any of the erection-boosting PDE5
inhibitors) increases testosterone post-exercise in healthy male subjects. 
So should you pop this pill before going to the gym? Well, not so fast:
the study also showed that Cialis amplified cortisol significantly more than
normal as well. The last thing most of us guys need is more cortisol, which
leads to muscle tissue breakdown, visceral fat deposition and other ills. In
