Increase Free Testosterone Levels
One of the factors which causes a decline in free testosterone levels is excessive binding of testosterone to carrier proteins, this divert it’s use in the production of other proteins/hormones, including estrogen.
Aging men sometimes convert testosterone to estrogen. The estrogen is then taken up by testosterone receptor sites in cells throughout the body. When an estrogen molecule occupies a testosterone receptor site on a cell membrane, it blocks the ability of free testosterone to induce a healthy hormonal signal. It does not matter how much serum free testosterone is available if excess estrogen is competing for the same cellular receptor sites.
The most common medical prescription to increase free testosterone is exogenous testosterone replacement. Obviously you should consult with a qualified doctor or endocrinologist about whether that route is appropriate for you at this time.
“Testosterone within the circulation is principally bound to proteins,
the most important of which is sex hormone binding globulin (SHBG).
Only about 2 percent of testosterone is unbound or free testosterone (bio-available) and therefore free to enter cells in order to effect its biological actions by binding to androgen receptors….”
“Hypotestosteronaemia levels [that is, low levels] quoted in papers
vary between around 300 ng/dl (10.4 nmol/L) and 400 ng/dl (13.9
nmol/L).”

“Bioavailable testosterone refers to the ‘free’ testosterone of the hormone unbound to carrier proteins which is able to act directly upon target tissues.”
You can not maintain or build muscle mass without having free/unbound testosterone in your body.

“It is well known that androgen levels decline in men with age.
Furthermore, as a result of the increase in binding capacity for
testosterone in serum, there is an early and more dramatic decline in
free testosterone, the physiologically functioning component of serum
testosterone, than in the total testosterone concentration….”
“The ideal therapy should consist of creating physiologic testosterone
concentrations (400 to 700 ng/dL in blood taken in the morning) and
restoring circadian variations.”

does working out the legs produce testosterone

Working out increases your Testosterone, hGH, and your IGF-1 levels. Since your legs are your largest muscles, I have read many times working them out causes, the biggest release of aforehand mentioned hormones.

Clearly people making remarks about working out or other such simplistic measures are not in the mid to late sixties and running into the fact that they are running out of life.
Let me tell you, if you don’t feel good… losing some bad years off the end of your life is a good trade off for feeling good and having a sex life while you are still alive.

I started taking Vitamin C with a Zinc compound and it’s made a world of difference in me. I was able to get up and start doing push ups in the morning (1 rep of 10 in the morning, another rep of 10 in the afternoon). I have been taking androgel and/or testim for years and it’s only been recent that the doctors finally told me that that stuff “TURNS OFF THE TESTICLES”. So ANY NATURAL FORMULA BEATS THESE PHARMACEUTICAL TREATMENTS IN MY OPINION (AT LEAST THAT’S WHAT I HOPE HAPPENS). Guys, Working Out Your Arms and Legs Helps A Great Deal!
