There’s a book called Secret Testosterone Nexus of Evolution, and it dives into everything; nutrition, training, sleep, and mental focus. It’s the real deal, my life hasn’t been the same since.

[@MoosaIslamic]

Summary: - Don't Overtrain ~ 4:52 (high volume/endurance add) - Body composition: Try to stay in 10-15% body fat range. - Caloric intake: Maintain minimum caloric requirements. 20-40% fats, ideally more saturated, reduce alcohol. - Deficiencies: Zinc, Vit. D - Get enough sleep, and don't do regular all-nighters - Get a girlfriend, regular sex - De-stress (meditate)

Anecdotally, many years ago when I was overweight and had zero motivation in life (literally did not leave my room) my T was about 280 ng/dl - very low. I had it tested the other year out of the blue when I was very healthy, active and doing things with my time my T was about 670 ng/dl. Healthy lifestyle physically and mentally are crucial for healthy T.

Can you offer some advice? I've been getting back to the gym. But recntly had testosterone checked in Decemver and my levels plummeted from 480 ng/dl to 284 ng/dl. I was in an extremely stressful time (and experiencing high anxiety). I'm working on stress, but what about weight training and diet?

[@TheFitnessChallenge]

@@FL-ur3wg Was both blood samples collected on the same time of the day? This can cause an affect, some medications as well, medical conditions, etc What did your Dr say when he viewed the results? It is possible that complete inactivity, stress and depression can have a strong effect in a short period of time but if that's the case regular exercise, healthy diet and seeking help with stress management. Exercise volume and intensity would vary from person to person based on their fitness level but as long as you are actively improving and doing more from day to day should do the trick. Same with diet, it varies from one person to another. What is a healthy diet for me does not necessarily mean healthy for you. Sleep is a big factor for a lot of reasons. Just like Dr Mathew Walker always says sleep is truly a super power. Discussing with your GP is the first and most important step. Have you been working out and improving your diet over the last month?

Nice treatment of the subject. Never paid attention to my T level until I had prostate cancer then started a continued research on the subject. What I have learned is that it is very possible that I got the prostate cancer from low T. My natural T was 400-469 but I was unable to build muscle no matter how hard I trained and worked out. I finally got with a good hormone doc and now have my T levels managed between the upper 500's to about 700. I am able to build muscle again and I am leaner (I think because of the T injections which are painless subQ). Everything you posted I found agreement with in the literature when I studied this. However be sure to make your readers aware that if you go external T supplementation that your testes will shrink from lack of need for them to produce T naturally. Using HCG no not HGH but HCG will keep your testes from shrinking. What science posts are "normal" isn't normal at all. We all have individual differences and need to tune our bodies to what level of T is effective for you. Going over 800 is pretty risky and most of the empirical date seems to point to a T level of 600-700 as ideal. From late teens on our T drops and if you want to be healthy and reduce chances of heart attacks keep track of your T and keep it in a safe not low range which is dangerous. I applaud this video as one of the best I have read.....

[@jaycampbell333]

^LOL. Going over 800 is risky? According to whom? Some Quack Doctor? FALSE! This video is a waste of time. There is no way to increase T naturally. The environment is lobbing a full scale assault on human endocrine systems. Unless you have elite top 1% genetics, by the time you hit 30 years old you will be on a direct downward descent into T deficiency. Best advice is to educate yourself via the TOTBible.com. After that get proper labs and if you find yourself deficient, make sure you work with a Doctor (unlike the Doctor this guy above is working with)who has an experiential body of work managing endocrine systems of both male and female patients for at least 5 and hopefully 10 years. Working with anyone else is a total waste of time and you'll wind up worse than where you started. Good Luck!

I liked this video, Jeff. I used improving my nutrition and regular weights and increasing overall activity while reducing stress and getting 8 hours sleep each night, as lifestyle changes. Overall, I came to reduce the intensity of my workouts, and adjusting for my age, and my testosterone increased from just over 200 at age 50, to, now, over 500 at age 53. So lifestyle changes which include age appropriate weight training and rest have been far more helpful than I would have believed possible. I thought old guys like me couldn't change T levels.

Noob question: Most guys at the gym usually focus on mass, bulk, strength, endurance. They wanna be pumped, ripped, and jacked. But what about people who want more slender athletic forms? Quick, agile, lightweight, responsive. Some lifting is always good ... some cardio is always good ... gaining, losing, or reconfiguring mass is always good ... but fixed reps and fixed weights seem counterproductive, variable reps with random weights seems more likely to simulate the sorts of muscle motions needed in sports. I seem to gain more _useful_ muscle from stuff like dance aerobics and floor sports (and even from random moderately-intense physical labour tasks at work) than I do from lifting structured sets and reps.

[@robertlehnert4148]

Working Out for increased natural T: Weight lifting is primary. Lift heavy weights, no "tone" 15-20+ rep crap and forgedabout bodybuilding multiple exercises (especially single body part isolation movements) and many multiple sets DO compound, multiple joint whole body exercises. Seriously, avoid machines whenever possible. NO isolation exercises for at least six months. So, this means squats, deadlifts, overhead (standing military) press, Bench Presses, Chin/Pull Ups, or Barbell/Kettlebell/Dumbbell rows. Research these three programs, choose ONE that works for you, and stick to it for at least half a year. 1. Starting Strength, from Mark Rippetoe 2. Power to the People or the Russian Bear program by Pavel Tsatsouline 3. Stronglifts 5x5 program. For cardio: walk with a loaded knapsack-- aka rucking. A Kettlebell Swing (RKB "Hard Style") Routine is a GREAT cardio and posterior chain exercise. This will not only improve your butt and your thrusting endurence, it is a proven T-builder. The KB weight should light enough not to interfere with your strength training but heavy enough to achieve results. Most men, starting out with a 35 pound KB is right. Get adequate sleep, improve your diet (natural saturated animal fat is actually crucial!), and get some actual sunlight on your head, if not your body. Sunlight produced vitamin D is incredibly important for making T as well as the proven psychological benefits, especially stress reduction, in regularly getting natural light and fresh air.

At 11:17 you concluded that testosterone levels are not affected by an ejaculation based on neurophysiology. That seems to be a very board conclusion that doesn't connect. You can't say because serotonin and nitric oxide release in the BRAIN that it doesn't bring the levels down in the BODY. Great video and informative.

Nice job Jeff. I'm 54 years old and I've been testing a variety of techniques to maximize testosterone. Other than the ideas you presented (heavy compound lifting, HIIT, no excessive dieting, Vit D, Zinc, hot women, exciting sex, plenty of sleep) I've also found that the following things make me "feel" like my testosterone is much higher (I haven't tested it in a lab): Tongkat Ali, Pine Pollen, Nettle Root, organic food, grass fed meat, natural soaps, toothpaste, shampoo, etc. I also stay away from plastic containers as much as possible. It is truly amazing how much better and more "manly" I feel since making these changes.

DUAL 777 plastic containers and natural soap? Really? Wtf. Also I can't believe anyone reasonable finds testosterone that important.

[@dual7779]

First of all, plastic containers and most generic personal care products contain endocrine disruptors and possible carcinogens. And this info ain't pulled out of ass. Don't believe, look up yourself. Now wIll it make significant difference when it comes to test? Who knows. Haven't seen any clinical trials or studies. The only way is blood test before and after to find out if there were any hormonal changes. So next time before you call someone an idiot, at least do some fuckin research.
