Weight Lifting Slowing Down Spartan Racers

Resistance Training Shown To  Decrease Performance Hormones Needed For Spartan Racing

Research held in the Human Performance Laboratory at Penn State University finds resistance training can significantly lower testosterone levels in men for more than 13 hours post workout.  

Why is this important?

Well, testosterone is one of three powerful hormones that gives you a performance advantage in any race. It’s also responsible for  keeping your body lean and muscular year round.

US Military Peobstacle course racing doctorrformance Division researcher Bradley Nindl and a group of experts are the first to test the negative effects of weight lifting in healthy males. What they discovered is shocking…

During the experiment, male subjects underwent rigorous blood sampling every 10-minutes for 13-hourspost-workout. This strict blood testing format has never been used on testosterone and exercise based experiments before…

The results were nothing short of groundbreaking. It raises a Red Flag for men who want a racing and fitness edge on the obstacle course with ripped and muscular body to match.

The male subject’s hormone levels remained “stunted” for 13 hours post-workout due to poor endocrine function. Researchers reported significantly lower total testosterone, free testosterone and luteinizing hormone levels. All important chemicals for optimal performance, muscle building, and producing what doctor’s call, “sex steroids” in your testes.

This is a problem.

Previously… lifting weights was known for increasing testosterone levels in men. However the results of this experiment showed a clear 15% decrease in total testosterone and 24% reduction in luteinizing hormone.

Even more shocking, two well-known weight lifting exercises, the bench-press and squat also lowered the participant’s testosterone levels. These, along with the latissimus pull-down machine and leg press.

Needless to say, the above research has flipped everything we thought about weight lifting on it’s head.

Our researchers then exposed more “testosterone killers”, including endurance training, a common practice for Spartan racers, Crossfit athletes, and Triathletes.


This type of training is shown to cause exercise-induced testosterone depletion to an evenMale-runner-tired-1 greater effect than weight lifting.

Male-runner-tired-1Male-runner-tired-1I’ve personally suffered the side-effects of exercise-induced testosterone depletion with this method of training. I almost destroyed my marriage. And I lost years of hard-earned muscle and strength in a few months. I was training harder, not smarter and my testosterone levels suffered because of it .

You may be experiencing the same side-effects I did. I developed a skinny-fat body and my love-handles would not disappear, even though I was exercising my butt off. It’s frustrating when you expect results but they don’t happen for you…

Fortunately, I came across a short and simple running technique that drove-up my testosterone and restored my muscle mass, with more to spare. Having me MORE than ready come race day. This new running method is now the “gold standard” workout for men who do cardio. And I make sure all of my clients know it.

There’s more. The experiment discussed “exercise junkie” workouts. The ones lasting for 60-minutes, most days of the week. Unfortunately, more bad news for gym rats. A massive increase in cortisol levels were confirmed…

This “stress-hormone”, when balanced with testosterone, is a good thing. However, long and intense workouts, multiple days per week can cause a cortisol imbalance – a dangerous “hormonal tilt” causing men’s testosterone levels to shrink while cortisol invades in your blood stream.

The side-effects are similar to those of andropause. Also known as “male-menopause”. Andropause can be triggered by any testosterone reducing activity.

You may be experiencing some of the symptoms right now:

  • Trouble losing fat, especially around the midsection and lower back region.
  • Low sex drive.
  • Fatigue and chronic “energy swings” throughout the day
  • Muscle loss or inability to gain muscle
  • Weight Gain
  • Depression
  • Anxiety
  • High blood pressure

tired-man-gym-6-reasons-not-fitBe honest with yourself. Are you experiencing any symptoms of andropause? If you are, consider changing your workouts immediately.

Last discovery from the research. Short and intense workouts are key for more testosterone and growth hormone. If yotired-man-gym-6-reasons-not-fitu’re a “gym rat” and refuse to cut-back your workout duration, you are putting your testosterone levels at risk and lowering your true performance potential with obstacle racing.

You’ll waste minutes or hours of your life on pointless exercise. You’ll receive NO benefit whatsoever other than losing a few more calories.

Instead, you’ll be blocking the only hormones that help men like you, build muscle, perform on race day, and even have sex. You’ll feel more like a caged animal. Like a hamster running endlessly on a wheel.

It’s a problem. The red flag list is growing. If you’re serious about increasing your testosterone levels and improving your racing performance, you can’t just accept any and all information these days. Most guys follow any advice as long as there’s a picture of a juiced-up bodybuilder on the cover. I was one of those guys once…

I know this information is daunting. It’s unexpected. These days you feel like everything is waging war against your manhood. And you’re right. It is! But it doesn’t have to be this way…

Amongst the muck of information out there, I stumbled across an ancient running technique scientifically proven to increase testosterone, boost VO2 Max, flood your body with growth hormone, and trigger greater blood flow muscle-pumping vascularity in men with only 16-minutes per week.

Will it work for everyone? No. Will it work for guys… undoubtedly.

Review the above. Are any of your workouts actually damaging your training results without you actually knowing? You probably thought the results you’re seeing are the best they can be…

Yet how will you know if you don’t “change it up” and try something new, right?
