If working out is good for you, then working out more can only be better for you, right? Not quite. Too many trips to the gym or cardio sessions could actually undo all of those gains you’ve been working towards. Worse, they might be doing damage to your heart, arteries and causing your brain to become addicted to exercise. Scary stuff!

Following is the transcript of the video:

Exercising is supposed to be good for you. It can help you stay at a healthy weight, improve your cardiovascular health, and even ward off depression. But like most things, it’s possible to over-do it. And getting too much exercise can have serious consequences for your body and brain. So, what exactly is “too much” exercising?

Well, it depends on factors like your age, health, and choice of workouts. But in general, adults should get around 5 hours a week of moderate exercise or 2-and-a-half hours of more intense activity. Or some combination of the two. That’s according to the CDC. But research shows that going way above and beyond that doesn’t increase your health benefits.

One unsurprising study found that light to moderate runners had a lower risk of death than people who didn’t exercise. But, in a surprising turn, some people who ran at a faster pace for more than 3 times a week had a similar risk of dying as the non-runners. So running too much, and too intensely, seems to undo some of the health benefits gained from regular running.

Extreme endurance exercises, like ultra marathons, may also lead to heart damage, heart rhythm disorders, and enlarged arteries, in some people. Experts believe extreme endurance puts extreme demands on the cardiovascular system. One study found that repeated extreme exercises can “remodel” the heart, thickening the muscle’s walls and scarring tissue.

Another study showed that women were less likely to have a heart attack or stroke, if they were physically active at least once a week. But that risk of heart attacks and strokes shot up for women who exercised strenuously every day. So, excessive exercise doesn’t provide more benefits than moderate exercise. And it could be more risky.

Women are at particular risk for what’s known as the “female athlete triad” that includes: loss of menstruation, osteoporosis or bone mineral loss and eating disorders. These symptoms usually arise from a combination of overexercise and calorie restriction.

For men, intense exercise has been shown to decrease libido. Possibly due to physical fatigue and lower testosterone levels. For both men and women, overexercise raises the risk of overuse injuries, like tendinitis and stress fractures. These injuries result from repetitive trauma. Your immune system can likewise suffer.

While moderate exercise can improve your immune system, excessive exercise can actually suppress it.

There’s up to a 72-hour “open window” of impaired immunity after intense exercise. This basically means viruses and bacteria might have an easier time invading and infecting the body. And athletes who overexercised also experienced more upper respiratory tract infections.

So, we know excessive exercise can wreak havoc on your body — particularly your heart, tendons, ligaments, and immune system. And for around 1 million people in the US, exercise addiction is wreaking havoc on their brains.

Symptoms of exercise addiction include withdrawal — that’s when you feel anxious or exhausted when you miss a workout. Or feeling a lack of control and unable to cut down on exercise. Even when you know it’s hurting you.

Now, it’s important to understand that you shouldn’t just give up on exercising. The key is to get the right amount.

So, feel free to go forth and run. Just not all the time.

    I go to the gym 6 times a week for 6 months now doing ppl split (and I do cardio 4 times a week), Ive made great progress in the gym but I've become extremely irritable and I tend to snap at my family I also can't cope with missing a workout.

  8. Anarchist Tutor

    I think Ellington Darden's recommendations are pretty good; read his latest book, though I don't agree with the cold water recuperation he recommends. Basically lift very intensely, slowly, and negative-focused, with plenty of recovery between workouts.

    I also think that cardiovascular exercise at Level 2 heart rate with occasional Level 3 and very occasional Level 4 can be good from what I've read/watched.

  9. Raghu

    Commandos like Indian para SF commandos ,US Navy seals do very very very hard workout as hell. What about them??

  10. here to avoid people

    idk why i get SO tired from working out like literally the next day after working out i sleep the whole day and my workout isn't even that intense ( some cardio and 2 ytb home workouts ) and not even like everyday barely 3 times a week that's the reason i stop working out

  11. mindstate prod.

    I workout fighting style for hours and hours over pushing through pain I torture myself I always start to see lights in my vision that's when I stop. I've always been an overachiever I'll work all day at my job then come home and go workout in the hot shed for 2 hours with no breaks intense cardio fighting no breaks to take a breather I push past my ability to catch my breath I don't care you know why. Because my results are absolutely monsterous. I used to struggle to spar in the boxing gym with guys for just 3 rounds. Now I can fight for hours it feels so good. And I have crazy ability , like I can dart in and out and side to side my foot work on 1 million. I'm an addict to these results. If you want results u must feel pain.

    I'll never, ever understand people who waste their lives in pursuit of an unattainable, and ultimately only ever temporary, ideal of "perfection". It's absolutely pathetic the way people seem to believe that conforming to someone else's standard of beauty and fitness will somehow make everything in their life fall into place.
    When you're on your deathbed, do you really want to be thinking about how much time you wasted at the gym, or allowing narcissistic paranoia to permeate every aspect of your life, to the extent that your external appearance is practically all you care about?
    Being stronger or fitter than someone doesn't make you any better than them. You're still going to end up rotting beneath the earth like everyone else. Excessive exercise and gym attendance is almost 100% born from narcissism, which is NEVER endearing and NEVER healthy. Stop caring about your superficial and meaningless "status" or "rank", they'r nothing more than self-imposed illusions. Don't ever buy into the idea that some people are "superior" to others, and don't ever convince yourself that you're somehow not good enough to be here. You're perfectly ok as who you are, and those who disagree are just weak-willed drones who can't think for themselves.

    But hey, if you want to waste your one and only life stressing and worrying about irrelevant superficial crap that is of no consequence at all, holding yourself to ridiculously high standards and beating yourself up whenever you fail to meet them, go knock yourself out – just don't expect much sympathy when you start whingeing about the pointless struggle you willingly chose to buy into.
