Mighty Endorphins: Training Intensity and Resistance Training

This essay from Marty Gallagher explores the elusive exercise-induced pleasure threshold: the way intense resistance training, bodybuilding, cardio, and progressive strength work can create a powerful sense of well-being that keeps serious athletes coming back. For lifters chasing that high, the lesson still holds: endorphins are not triggered by easy, casual effort; they are earned through disciplined training, escalating intensity, and a physical culture built around real work with dependable strength training equipment.

Mighty Endorphins

In white-hot pursuit of the exercise-induced pleasure threshold

"In my experience there are two types of elite bodybuilders: those that love to train and those that don't. A man can be good at something - even great at something - but not necessarily like or love the pursuit or thing he excels at. I have seen this phenomenon in bodybuilding repeatedly. Men that win titles and fame that don't really like to train. These men are motivated by the fame, the adulation, the attention and the financial benefits. When they retire they quit training.

On the other hand you have those that love to train; they love the methodical nature of progressive resistance training; they love the physical and emotional effects of an intense training session; they love the camaraderie of training with like-minded training partners and they love every aspect associated with ‘putting in the work.' This type never quit, never give up and as a result they live longer and are healthier and tend to be far more psychologically balanced."

"My theory is that it's the endorphins that keep us coming back for more…"

As we've indicated previously, the single most overlooked aspect in triggering an utter and complete physical transformation is readjusting the mindset of the trainee as it relates to the transformational process. Unless the individual finds a way to derive intense pleasure from all aspects of "the process," as Iron Icon Bill Pearl mysteriously calls it, adherence and success become problematic. Those able to love the training and the disciplined eating are those that succeed.

Learning to love the process is multilayered and complex: there is the physical adherence and psychological adherence; there is instantaneous gratification and delayed gratification; there is the pleasure of taste and the pleasurable physical sensation that accompanies intense physical exercise. The Brain Train journey begins by examining the pleasure associated with extreme physical effort.

Endorphins and the Exercise-Induced Pleasure Threshold

Another widely publicized effect of endorphin production is the so-called "runner's high," which is said to occur when strenuous exercise takes a person over a threshold that activates endorphin production. Endorphins are released during long, continuous workouts when the level of intensity rises from moderate to intense. To generate an endorphin release, the person needs to go past his or her body's physical limit.

Endorphins ("endogenous morphine") are endogenous opioid peptides that function as neurotransmitters. They are produced by the pituitary gland and the hypothalamus in vertebrates during exercise. Endorphins are released in conjunction with excitement, pain, spicy food, hot love, orgasm and killer training sessions. Endorphins are often described as the body's own morphine-like substances; their ability to produce analgesia generates a feeling of well-being. The actual word, endorphin, has two parts: endo- and -orphin; short for endogenous and morphine, literally meaning "a morphine-like substance originating from within the body."

Endorphin Addicts and Intense Resistance Training

Endorphin Addicts: Gallagher & Yates, 2010. Marty and Dorian 2010: Yates, 6-time Mr. Olympia, is a training genius and a complete Purposeful Primitive. Both his training and nutrition have a decidedly British, matter-of-fact simplicity about them.

Intense progressive resistance training is an endorphin stimulator without peer. Cardio done with great intensity also triggers the release of endorphins. Any elite athlete knows the feeling of intense well-being and satisfaction that accompanies a brutal workout. My pet theory is the elite are endorphin addicts. The Mighty Endorphins are what keep the elite coming back for more.

Yates trains like a powerlifter that uses forced reps. He eats sensibly and has a lot of latitude, compared to his zealot bodybuilder brethren. Yates is a serious student of training strategies and tactics; he loves the process and knows all about the endorphin rush that accompanies bone-crushing poundage. His approach towards nutrition is refreshing: he includes beef and bagels and fruit into his diet. He never dropped below 3,500 calories, hardly starvation, even in the final days leading up to another Mr. Olympia win. His seminars were reaffirmations of the ultra-basics: no magic or hidden rabbit secrets here; straight ahead advice that was unvarnished and always the unbiased cold truth.

That ultra-basic mindset is the same reason serious bodybuilding and powerlifting spaces still begin with the fundamentals: free weights, a dependable powerlifting bar, quality urethane Olympic plates with grips and the kind of training environment that rewards effort instead of shortcuts.

John Gamble and the Old School Powerlifting Effect

This photo of immortal power God John Gamble, circa 1985, expresses and exemplifies everything mighty and righteous about Old School powerlifting.

John is shown ratcheting into place one of his numerous 825-840 pound deadlifts. He would routinely pull this big AFTER having squatted 881 and benched 580 in a t-shirt. John would open his deadlifts at, say, 788, leap to 820, crush it, and then give 840+ a ride. In his day, in his class, he was unbeatable. Look at the physique: lean and chiseled, weighing 275 standing 5-10. He'd routinely drop 20 pounds in the final 24 hours leading up to a competition. Gamble exemplified the benefits of hardcore progressive resistance. He was truly a Man amongst men. Gamble was an all-around great athlete.

For modern powerlifters, bodybuilders, first responders, military athletes, and serious home gym trainees chasing that same high-effort training effect, the support equipment matters. Heavy pulling and squatting call for secure Lock-Jaw Sport barbell collars, dependable Made in USA leather weightlifting belts, durable heavy-duty deadlifting mats, and resilient rubber gym flooring that can stand up to repeated intensity.

Why the Process Matters More Than the Prize

The fame-driven bodybuilder and the process-driven bodybuilder may both win titles, at least for a while, but Gallagher's point is that the lifter who learns to love the process has the advantage that lasts. Endorphins, camaraderie, physical exertion, discipline, heavy iron and the satisfaction of a hard session create a feedback loop. The more deeply the trainee connects effort with pleasure, the more likely the trainee is to return and repeat the behavior.

This is why the best training equipment is never a substitute for intent, but it does remove friction from the process. A well-built training space with dumbbells, barbells, weight plates, commercial power racks, and durable flooring gives the athlete fewer excuses and more opportunities to cross the threshold where training becomes its own reward.

Equipment Pairings for High-Intensity Training

High-intensity resistance training does not require gimmicks, but it does demand equipment that can support hard, repeatable effort. Lifters who train heavy and often may benefit from practical accessories such as Schiek power lifting straps, perforated neoprene knee sleeves, and Power Series weightlifting gloves when those tools fit the training goal.

Facilities building around bodybuilding, powerlifting and general athletic training can pair foundational strength stations with versatile options such as rubber hex dumbbell sets, PowerBlock Pro 50 commercial dumbbells, premium rubber bumper plates, and dedicated weightlifting platforms. The equipment does not create the endorphin rush by itself; the athlete's effort does. The equipment simply makes the hard work possible, repeatable and sustainable.

FAQ

What are endorphins in exercise and resistance training?

Endorphins are endogenous opioid peptides associated with feelings of well-being and analgesia. In the context of this article, Gallagher focuses on the endorphin rush that can accompany intense resistance training, bodybuilding, cardio and other demanding physical effort.

Can bodybuilding and weight training trigger endorphins?

Yes, intense weight training and bodybuilding sessions can be part of the exercise-induced pleasure response Gallagher describes. His central point is that the effect is tied to effort, intensity and the trainee's relationship with the process.

Why do elite athletes keep coming back to brutal workouts?

Gallagher's theory is that elite athletes are, in a sense, endorphin addicts. They return not only for results, titles or physique changes, but for the intense satisfaction and well-being that follows a serious training session.

What does Bill Pearl's quote add to the article?

Bill Pearl's quote separates athletes who merely like the rewards of bodybuilding from those who love the work itself. Gallagher uses that distinction to show why mindset, adherence and pleasure in the process are critical to long-term training success.

What equipment supports high-intensity resistance training?

A serious setup starts with strength training equipment, free weights, barbells, dumbbells, weight plates, racks, flooring and practical accessories that support safe, hard, repeatable training for powerlifting, bodybuilding and athletic performance.
